He needs to handle a Magpul 870 stock set up , its great . I have it on my Slug gun for Ohio Deer hinting & its a world of difference compared to a Factory set up . You can change the stock length with different recoil pad thickness & different cheek risers . I have photo's around here some where , if not I will dig her out & take some more photo's .

Feeding & then extracting a loaded round will almost always leave some kind of marks on the Bullet & brass to some extent , not from feeding , its from extracting . Every one is jumping on the Barrel , what if its an issue with the Upper Receiver ? I can't see the rest of the Barrels extension to see how it mates within the Upper Receiver to tell if its seated to far in . Lock the BCG back & Insert a loaded Magazine & see how the actual loaded rounds (dummy rounds preferred ) line up with the feed ramps , does the lowest sitting round look like it will feed & hit the Upper receive or will it feed onto the Feed ramp on the Barrel extension ? You don't have to feed any ammo to see this through the Ejection Port . One other thing , the Firing Pin locks the Carrier Cam Pin in place , with out the FP , you could really lock up the BCG into the Receiver . Personally , I would test fire the rifle if Head Spacing is correct .

I have said it before , Carolina had a weak schedule & I'm sorry to say this to all the Arizona fans , but they were no match for Carolina . Denver will be a different story for Carolina . Cam's arrogant & he has an a$$ whooping coming , but should be a good game .

I guess it starts , got an email apologizing that it was out of stock ( even though it was shown to be " in stock " ) & will have more in on Thursday & they will ship it then . At lest they say they will not charge my CC till it ships . I'm in no hurry any way , but don't let them know .?

Has anyone felt with them before , how do you rate them ? I ordered a BRO Upper Receiver from them yesterday & was wondering if I should worry . ( kinda late now to think of that ) ðð¼

That is one nasty looking Buffer in the above photo's .? The BATF/E length requirements are on barrel length , if its 16" & over , a folding stock is legal ( what State you live in may have other requirements ), now when you get into shorter Barrel , well , that gets into SBR , no matter what stock you have . Then , if its a Pistol , no stock is legal , folding or not .

I personally prefer a Rifle length gas system when the 308 cartridge is involved . Helps with recoil slightly & less stress on cycling components . I have rifle length gas systems on three 308AR's , 16",18" & 20 " barreled rifles . You choices in Barrels are top notch , there are less expensive alternatives , that have the reputation to shoot better then most of us can , IMO , but buy what you like , you can't go wrong with your choices . 18" is a good choice , but for hunting , I would use my 16" , that 2" doesn't sound like much , but the shorter barrel swings around faster & is slightly lighter . I see only a slight difference in grouping between the length of the barrels @ 200 yards .All three of my Barrels are Criterion Barrels .

I like mine also , didn't cost me a thing , except to replace the gas cylinder when it empties . Mine is more work , because I have to insert & remove the case , but it goes real quick. Ya , that one was coking a bit long ..

Now , that , was funny ?

I think Carolina will have problems with the Denver Defense , Defense will win the game . I think Carolina really had a weak schedule & it will show , in the Bowl . JMHO My pick is Denver wins SB 50 .

Is that all , then give me two ?

Don't think that 25 cal. Bullet will even chamber in a 5.56/.223

Aluminum Oxide Polishing compound from Brownnells & a Marble Lapping table , I lap a lot of Parts for Firearms & Vintage Harley's .

Just makes it sweeter at the end of the build , to go out & bust some cap's .?

I prefer the AR 10 Mag Catch , to the the DPMS . I have some photo's of the difference around here some where as well as the differences in the measurements . The AR 10 has a longer threaded stem , for the Button , for one .

There was a 30'06 AR built, I see Noreen had a BN36 at the 2014 shot show .

I would like one , probably out of my spending limits though .

There is a Member here " Toolndie7" who wants to make a run of them for a 308AR , PM him here . He is good at what he does . He may see this & speak up . I might be forced to purchase one from him myself if he makes some .?

Yep , if you look at the photo's in my above post you can see I have two PMag 20 rounders in one of the pouches , but of course the PMag 25's don't fit .

I think it was a " hit " on the Ambassador , he knew something about Clinton or O'Butthead ( maybe my foil hat is too tight today? , just didn't work out the way they wanted , but did have the end result . No doubt they left those people hanging , ripe for slaughter .

I too like the Shirt, but also like the Dogs Muzzle !

PSA has proprietary component issues , its been discussed here many times .

Well I see its a Large Frame AR . The gas Tube is definitely too long , of course you already knew that . This was asked already , but could you measure the length of the Gas Tube out of the Rifle . Aprox. Gas Tube length for an AR : Pistol--- 4.5" Carbine - 7.5" Mid.----- 9.5" Rifle ----- 13" Armalite lengths, Rifle ( 308 ) ----- 15.5 " Carbine ( 308 )--12 1/16" super SASS Carbine ( 308 )--11" Super SASS< Rife (308 ) ? Mid ,( 223 )------------------ 11 3/4" Carbine ( 223) --------------- 9 3/4 " Rifle ( 223 ) ------------------- 15 3/16" National Match--------------- ? These measurements should get you close to what you have & may show you what you need . AR-15 Gas System Sizes There are four common AR-15 gas system lengths: Pistol, Carbine, Mid, and Rifle. Each length utilizes different sized gas tubes and placement of the gas block. Although you can use nearly any sized forearm with any length gas system, it's important to know what the lengths are if you desire a concealed gas block (under the handguard). If you don’t know what size system you have, measure the handguard or distance to the gas block to quickly determine. Below are the common dimensions. Pistol-Length Used on very short barrels, usually 10″ in length or less. Gas Tube Length: Approximately 4.5” Handguards or free-float tube Length: Generally between 3”-4” in length. It's common to install a low profile gas block and conceal it under a carbine length free float forearm like the YHM Diamond YHM-9630-DX for more accessory space and better grip area. Carbine-Length Most common length gas system. Usually found on barrel lengths from approximately 10”-18”.es of AR-15 rifles. Gas Tube Length: Approximately 7.5” Handguards or free-float tube Length: Generally between 6.5”-7” in length. For a concealed gas block look, buy a free float tube 9" or longer like the Spike's Tactical BAR 9". Mid-Length Commonly used on barrels from 14”-20”. Gas Tube Length: Approximately 9.5” Handguards or free-float tube Length: Generally between 8.5”-9” in length. For a concealed gas block look, buy a free float tube 10" or longer like the Midwest Industries T10. Rifle-Length Found on rifles with 20" or longer barrels. Gas Tube Length: Approximately 13” Handguards or free float tube length ranges from 11.5”-12” long. For a concealed gas block look, buy a free float tube 13" or longer like the Midwest Industries SS-15.

This is a fairly good description of what happens with the Brass Case when you pull the Trigger, its kind long read. The following is a specially-adapted excerpt from the forthcoming book,” Top-Grade Ammo,” by author Glen Zediker, owner of Zediker Publishing. Click here to order. Bear with me! We’ll get started on the process of handloading next time when I talk about setting up a sizing die. But before that, it’s good to keep in mind what we’re dealing with, and that is a cartridge case, and also what happens to it during firing, which is what we’re setting out to remedy when we reuse it. Rifle cartridge cases are made of brass, well, the reusable cases are (they can and have been made from steel and aluminum). There are no brass mines; brass is an alloy composed of copper and zinc and sometimes tiny amounts of other metals, like lead. The mix is usually about 70/30 copper to zinc. Different manufacturers use a different mix or blend, and that influences the nature of the material, and more about that shortly. When a round is fired, here’s what happens. When the firing pin or striker point contacts the primer, the cartridge is driven forward into the rifle chamber (as far as it is able to go). When the primer detonates and its flame enters the cartridge-case flash hole to ignite the propellant, gases are produced that begin to expand the case. As the propellant is consumed, gas pressure increases, the case head is driven backward against the bolt face, and the case neck and case shoulder are pushed forward as the case neck expands to release the bullet. The case essentially swells up like a balloon to fit the chamber, to the limits of the chamber, and this expansion is in all directions. So the back of the case is pushed into the bolt face and the front area is pushed or blown forward, while, during this, the case body is sealing (essentially sticking to) the chamber walls. A cartridge case begins to contract just about immediately after it expands. The firing process takes scant milliseconds. Brass is both elastic and plastic. “Elastic” means it will stretch and contract. “Plastic” means it will stretch and stay. The elastic quality makes it expand and seal the chamber and then shrink back enough to be removed or extracted from the chamber. Plastic qualities mean it will also have sustained permanent change. Well, some of it isn’t really permanent because it can be changed again using tools, but some changes are permanent, whether they are literally smoothed over or not. Some cases tend to be harder — less plastic and less elastic — and that is almost always good, or so I say. It’s easy to see that since brass used in a semi-auto has to deal with at least some premature bolt unlocking, a harder composition is less “sticky” in extraction. Even for a bolt-gun, though, harder alloy tends to be smoother cycling. In a semi-auto, case life is strongly influenced by brass composition, and the harder the longer. Thinking about what happened to the case, what it went through, during firing means we can anticipate the results and effects of dimensional changes. The areas of the chamber that have the greatest dimensional difference between those and the loaded round will have the greatest influence on the dimensions of the spent or fired case. Specifically, the spent case neck will now be too oversized to hold a bullet in place. The case shoulder will have lengthened (elevated if we’re standing the case on its bottom). The case body will have gotten larger in diameter. The case will also have lengthened overall (more about this in another article). What else? Some case material will have moved forward (brass flows in firing) toward the case neck. This material will have come from the area around the case head. The primer pocket will be larger in diameter. Each firing, brass gets harder overall. In the areas where it expands the most, it gets even harder as it is “worked” through expanding and then being contracted. The tools we use to restore dimensions, the sizing die for good instance, create the contraction. And as suggested, the wall area near the case head gets thinner and the case neck walls get thicker. All this means quite a bit to the handloader. First, get a clear picture of what’s happened to the spent cartridge case. Essentially, it’s expanded to more closely match the chamber dimensions. Of course, that means different spent-case dimensions from different chambers. Likewise, not all brass cases expand, or stay expanded, in the same way. Case capacity, by the way, isn’t always as important as it might seem. Greater volume does mean more room for propellant, and expanding gases. With faster to medium propellants, it’s a “trade,” in a way of looking at it. A little less propellant in a little smaller capacity case nets about the same as a little more propellant in a little larger capacity case. Pressure and velocity will be about the same, either way. Now, in larger cartridges, and also often with double-base propellants in any size cartridge, more internal volume will very often mean more velocity at suitable pressure. Point is, don’t worry too much about more or less case capacity in .223 Rem. or .308 Win. I think the alloy composition is more important. Now we can get started on patching them back up for another use…

I think I have some loaded 20rd.PMags in mine , but maybe not .I have to look .
