You tune the antenna to match the ohm output of the radio. Most Ham radios are 50 ohms, not sure about CB's. To do that right, you need an antenna tuner. Some antennas have tuning mechanisms in them, but can get rather trickey in the set up. Read the instructions, read them again, and then again. Then follow the instructions when tuning. Yes there are minimum and maximum distances involved for maximum performance. Those should be specified in the radio and antenna manuals. The antenna is just as important as the radio itself. People will go out and get an expensive radio then hook it up to an antenna that is nothing more than a coat hangar. And just as there are many flavors of radios, so there are many types of antennas. For vehicle mounting, you are pretty limited in the types, but there are many of those to choose from. I would bet that Universal Radio has what you are looking for. Finally, there are shops that will do the installation. Drilling holes and running wires in the right spaces can get tricky. Your local radio shack should be able to provide some references. If not, check out where the HAM guys get theirs done.

Me too. Especially if the "friendly foreign country" was France. Imagine that - never fired, only dropped once......

For DPMS Style .308 barrel extensions. http://www.midwayusa.com/viewProduct/?productNumber=722167#productTabReviews But take a look at the description: Midway assures me that the 1" drive ratchet is accurate. That is a HUGE ratchet - torque up to and over 600 pounds. Some of these use a 5 foot bar! Ratchet head is a good 3 pounds plus. I have seen 1" ratchets used on railroads, large and I mean large farm and industrial vehicles and equipment, but a .308 barrel? How much torque do those extensions require???? Heck, you can start out with a 1:10 twist, and by the time you are done ratcheting the extension down, you could end up with a 1:4 twist!!!! Really!!!!!

Yes, that is how I am reading it.

I have not seen the languag eof the bill, so I don't know how far the powers of this new "politbureau" will extend. But, even if it is limited solely to spending cuts, the fact that representation is half Republicans and half Democrats is a win for the Democrats. The last Congresisonal election resulted in a huge shift in the House of Representatives from Democrat controlled to Republican. That shift was brought about by the citizens of the United States. There was overwhelming support to move the Country into a more fiscally responsible position. Which meant, Dems out, Repub's in. Fiscal conservatives now control the House, and may control the Senate after the 2012 election. Which would allow sane fiscal poilcies to prevai, based on the vote of a majority of Congress, reflecting the wishes of the people. What this super congress does is to take away the advantage of a majority, which also eliminates the choices of the electorate. It resets the representation to the advantage of the minority party. The Constitution vests the power to legislate in Congress. Congress is comprised of one representative per voting distirct in the House, and two Senators from each State. No where does the COnstitution allow representatives to oursource their duties and responsibilities. Nor cede their powers or authority. Yes, Congress is certainly empowered to create "commissions" and committees. But Commissions and committees have no power per se to legislate, and are always required to present their report sand views to the entire Congress for a vote. Call is laziness, cowrdice, whatever - Congress has chosen to abdiucate its responsibilities to their constituents to some veiled group who may very well operate in the shadows. They now have to take no blame for the hard decisions, since it is "out of their hands". The Republicans ought to be feeling like Charlie Brown about now. Lucy has jerked the football away again!

Interesting. Take a look at the threaded barrel port on these receivers. Check out the second image of the DPMS receiver in this link: http://www.brownells.com/.aspx/pid=43844/Product/_308_AR_STRIPPED_UPPER_RECEIVER Now the image of the Iron Ridge upper from their website: http://www.ironridgeguns.com/ira-x-complete-lowers/ Now the image of the SI Defense Upper: http://shop.si-defense.com/SI_Defense_308_7_62_Generation_III_Upper_Receiver_p/si%20308%20upr-dpms-gen3.htm Iron Ridge has an unthreaded portion at the front, and puts the barrel pin slot in the unthreaded portion (as opposed to cutting it into the threaded portion like DPMS and SI). In addition, the barrel threads on both the DPMS and SI uppers go the entire length of the barrel port extension on the receiver, where Iron Ridge has both a front and rear unthreaded portion. A recent poster over at AR 15 noted that the BCG was about 1/8" from the buffer when the receiver halves were locked in. The unthreaded part of the IR barrel port measures about .1685". An eighth of an inch is .125", and 3/16 is .1875". Just wondering whether this is where the issue lies.

Holy smokes! .308 caliber! 1.5 pound aluminum barrel with a steel liner! Gas Impingement, Stoner design! 6 3/4 Pounds total weight! 20 round mags with optional 20 pound, 500 round belt-fed backpack! http://jeffersonian.name/g1957/G0357.pdf Back to the future with an AR 10! That article was written in 1957.

Check this out! Aluminum block for both AR 15 and AR 308 uppers. Flip it over for rail work. http://shop.si-defense.com/AR_15_and_AR_308_Upper_Receiver_Vice_p/si%20upr-vice.htm I wish this was available a year ago!

Will it also make your hands soft and silky smooth? ;D I am interested to see how this works. Getting tired of picking out crushed walnuts or corn cobb out of primer pockets.

Threaded barrel extension on the receiver is .687". .1685" to first thread from front.

I happen to have a Starrett Depth Gauge and a stripped Iron Ridge upper receiver. I can take a few measurements of the upper. Anyone have any suggestions? I thought the barrel thread would be a start.

Then read this: http://www.foxnews.com/politics/2009/04/02/myth-percent-small-fraction-guns-mexico-come/ Having been outed on their prior "90% of guns used in crimes In Mexico come from the US" mantra, a cynical individual could conclude that the program was intended to turn that into a legitimate statistic. The battle for public policy shifts is a struggle, and it generally takes a number of events or findings to begin to sway the public's view. Certainly, a significant increase in homicides from "illegally sold" weapons would get the public's attention. Were they going to disclose this program to the public at some point, it let it remain concealed and let the public draw its own conclusions? It is illegal to sell to straw buyers. The feds have prosecuted dealers for this very issue. So if it is illegal, does a federal agency have the power to direct others to break the law? What if, instead of illegal gun sales, it was murder? "We want you to kill someone so we can see who shows up at the funeral"? Last time I checked, federal employees were also subject to the laws of the US and the states.

You just tried these reoads in a new rifle, so I take it that before reloading, those rounds were shot out of a different rifle? Bolt or semi auto? If you are using reloads previously shot out of a different rifle, so, unless you properly full length resize, that brass you use is going to be fireformed to the dimensions of the chamber in the other rifle. Meaning? Was it not set correctly? That means the brass was jammed into the chamber, and the chamber was probably tight enough that to try to seat, the bolt the neck got pinched to ram it in. With a .308/7.62 x 51 the round does not seat off the rim; it seats off of the shoulder of the case. The "datum line" is the critical dimension (a point about halfway down from where the case neck starts its taper to where the neck taper stops). Overall case length is not unimportant, but proper headspace is what its all about. What kind of chamber does you new rifle have, versus your old rifle? Are they both .308 or is one a 7.62 chamber? Is it a match chamber, Obemeyer, etc.? The reason I ask, is that while a .308 will chamber just about any 7.62 x 51 round, because of the small differences between the two, a .308 (designed for chamber pressures of 62,000 PSI) will not necessarily work in a 7.62 chamber (pressures of 50,000 PSI). If you really want to nail it, take a couple of newly fired cases from your new rifle and send them to Hornnady or Forster (I think Forster will do it). They will ream your dies to the actual dimensions of YOUR chamber. If you reload, and especially if you are reloading for more than one .308, you need to grab something like this: http://www.jprifles.com/1.5.1.3.php Wilson also makes them. I like the JP since it does both OAL and headspace. Where football is a game of inches, reloading is a game of thousandths and tens of thousands. That's why your higher quality precision gauges are all calibrated to a margin of error in tens of thousandths or hundreds of thousandths. Finally, if you jammed a case in your new rifle hard enough that caused you to have to knock it back out from the bore, check our your chamber. Some guys run a Q-Tip in there to see if there is any snag to the cotton. If there is, or if the chamber is scratched, you may need to get the chamber polished to remove the blemish. Welcome to the world of reloading! A true lifetime learning process!

That is a great looking camo job! There are plenty of hogs that need a rendevous with a .308.

I might follow up with them, but I really wanrted to know whether anyone had any experience with the MGI adjustable tube? That would allow me to use any lo pro block.

Fulton makes a version of their Titan with a side charger as well.

Here is the text from my question to them: And their response: Maybe because I have to use a .875 gas block? That's why I was looking at the adjustable gas tube.

A Pri Gen III is what I am using.

Anyone have any experience with this: http://www.brownells.com/.aspx/sid=25948/pid=9947/Product/Rifle_Gas_Tube Great concept, just don't know how well it works. I need a .875 gas block, and the PRI Adjustable Lo Pro is too high for the handguard I am using (confirmed by PRI, which leads me to question why it is called low profile...)

I was able to track down the OP, and he confirmed that with both a factory-assembled DPMS upper, and with a factory DPMS upper with the same barrel and barrel extension and BCG, the BCG would make contact with the buffer when the uppers were put together in the IR lower. When he used the same BCG, barrel and extension on the IR upper, there was no contact between the BCG and the bolt. Assuming the two DPMS uppers were to DPMS spec, it seems the issue is with the IR upper.

Dumb questions Are the Tubb CWS and the BCM extractor upgrade kit the same for .223 and .308?

The only thing that argues against the buffer retaining pin hole being the issue is that the OP noted everything worked fine with a DPMS upper on the IR lower.

Luk 22:36 Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one.

I can't pick just one...... "Firearms stand next in importance to the constitution itself. They are the American people's liberty teeth and keystone under independence … from the hour the Pilgrims landed to the present day, events, occurences and tendencies prove that to ensure peace security and happiness, the rifle and pistol are equally indispensable … the very atmosphere of firearms anywhere restrains evil interference — they deserve a place of honor with all that's good." --George Washington Laws that forbid the carrying of arms, disarm only those who are neither inclined, nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants. They serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man. -- Thomas Jefferson, 1764 “The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.” --Thomas Jefferson Papers And what country can preserve its liberties, if its rulers are not warned from time to time, that this people preserve the spirit of resistance? Let them take arms…The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants. --Thomas Jefferson, Letter to William S. Smith 13 Nov 1787 Those who beat their swords into plowshares usually end up plowing for those who didn't. -- Ben Franklin Arms discourage and keep the invader and plunderer in awe, and preserve order in the world as well as property... Horrid mischief would ensue were the law-abiding deprived of the use of them. --Thomas Paine A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government. -- George Washington Guard with jealous attention the public liberty. Suspect everyone who approaches that jewel. Unfortunately, nothing will preserve it but downright force. Whenever you give up that force, you are ruined…The great object is that every man be armed. Everyone who is able might have a gun. --Patrick Henry. Are we at last brought to such an humiliating and debasing degradation that we cannot be trusted with arms for our own defense? Where is the difference between having our arms under our own possession and under our own direction, and having them under the management of Congress? If our defense be the real object of having those arms, in whose hands can they be trusted with more propriety, or equal safety to us, as in our own hands? -- Patrick Henry, 3 Elliot, Debates at 386. The Constitution shall never be construed to authorize Congress to prevent the people of the United States, who are peaceable citizens, from keeping their own arms. --Samuel Adams, debates & Proceedings in the Convention of the Commonwealth of Massachusetts, 86-87. The right of the people to keep and bear…arms shall not be infringed. A well regulated militia, composed of the people, trained to arms, is the best and most natural defense of a free country… --James Madison, I Annals of Congress 434 (June 8, 1789). (The Constitution preserves) the advantage of being armed which Americans possess over the people of almost every other nation…(where) the governments are afraid to trust the people with arms. --James Madison. If the representatives of the people betray their constituents, there is then no recourse left but in the exertion of that original right of self defense which is paramount to all positive forms of government... -- Alexander Hamilton, The Federalist (#28) . The best we can hope for concerning the people at large is that they be properly armed. --Alexander Hamilton, The Federalist Papers at 184-B. [W]hen the resolution of enslaving America was formed in Great Britain, the British Parliament was advised by an artful man, who was governor of Pennsylvania, to disarm the people; that it was the best and most effectual way to enslave them; but that they should not do it openly, but weaken them, and let them sink gradually...I ask, who are the militia? They consist of now of the whole people, except a few public officers. But I cannot say who will be the militia of the future day. If that paper on the table gets no alteration, the militia of the future day may not consist of all classes, high and low, and rich and poor... --George Mason The militia may be here destroyed by that method which has been practiced in other parts of the world before; that is, by rendering them useless – by disarming them. --George Mason Before a standing army can rule, the people must be disarmed; as they are in almost every kingdom in Europe. The supreme power in America cannot enforce unjust laws by the sword; because the whole body of the people are armed, and constitute a force superior to any band of regular troops that can be, on any pretence, raised in the United States. A military force, at the command of Congress, can execute no laws, but such as the people perceive to be just and constitutional; for they will possess the power, and jealousy will instantly inspire the inclination, to resist the execution of a law which appears to them unjust and oppressive. ---Noah Webster, An Examination of the Leading Principles of the Federal Constitution (Philadelphia 1787). [T]he unlimited power of the sword is not in the hands of either the federal or the state governments, but where I trust in God it will ever remain, in the hands of the People. -- Tench Coxe, Pennsylvania Gazette, Feb. 20, 1788. Among the many misdeeds of the British rule in India, history will look upon the Act depriving a whole nation of arms, as the blackest ... if we want to learn the use of arms, here is a golden opportunity. --Mahatma Gandhi, An Autobiography (page 446). If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun. Not at the head, where a fatal wound might result. But at some other body part, such as a leg. --The Dalai Lama *(obviously not skilled in the use of deadly force and "center of mass").
