Free Float vs Drop In Rail ?.
mrraley replied to Mr B's topic in AR-10 General, Technical Discussion
The SWS E1 is a really good handguard. It does take some time to ensure that it is level and straight though. I have installed one on my rifle. If you need it installed, either find someone that is familiar with this system or depending on how much beer you have, I could install it... <thumbsup> But unless you are looking for accurasy or function will determin if you want to free float or use drop in handguards. -
Now that I have a better idea of what you are trying to accomplish. The best idea that I can come up with would be to go with the AR-10 NM free float railed handguard and cut the last lug and slot off. Doing this will give you an extra 5/8” of room on the flash suppressor and not take anything away from the looks of the handguard itself. IMO this would be the best option because no matter what handguard you buy it is going to be the regular rifle length and cover the tail portion of the flash suppressor making it difficult to reach that locking leaver. <dontknow>

one way or another, you will either get or find answers on here. Weather you are looking for the ArmaLite AR-10 or another brand of .308 rifle, it is here. <thumbsup>

Another one you might want to look at is SWS http://www.superiorweaponssystems.com/products.htm

Could you post pictures to help get a better idea please? Depending on where the release is I might be able to trim the hand guard to make one work.

Im a little pissed at Armalite.

NEVER say that's not possible because it happens all the time in shipping. but in trying to figure this out... what was the condition of the egg crate foam in the case? Where were the additional pieces in the case? i.e magazine, sling The reason why I'm diggin at this is because I know for a fact that the rifles are checked at lease three times by QA. Once after assembly, during the test fire (with a minimum of 5 rounds if not 10), and before packaging. Before packaging, they are given a light cleaning but not a thorough cleaning. Do you have ANY idea of what type of man hours that would take for that? and on the amount of rifles they ship out a day. What this boils down to is that you need to look at the big picture before trying to place a blame that you have no idea on. There are a lot more moving parts here that what you are considering. If not call them up, get your trophy rifle sent in for touch up, make it look pretty, mount it on the wall and call it good. -

Just a thought.... Did you ever think that it might have happened during shipping? Have you ever seen how the guys in the big brown truck handle boxes? -
Something you might want to look into is if the rra is certified to be used as such.

since I can only choose one.... it had to be ArmaLite... thats what I had in Afghanistan.

You got to do better than that... I made this for my daughter and shoot it too. <munch>

AR10A Magazine Catch in a DPMS/KAC styled (SI-Defense) lower

Don't blame me, it wasn't me.... It was the one armed man... <laughs> -
If you go to the blog and actually look at some of the replies that are posted on there the sheeple are following closely on every word he says.

I was told one time, that for a percision rifle the DI would be better and with select fire rifles the piston is better. I do not have any experience with the select fire rifles in a piston system so I can not judge them on that. But with you bringing that up, edgecrusher, it puts more credit into it for me than hearing it from just one person that I wasnt sure with in the first place. Another point that I wanted to add is that a piston system also has more moving parts now too.

in on 1... <munch>

But on to the point! Nothing is perfect, and in seeking to make it perfect, we do in fact make it better. Those who are invested in doing this one way will resist any deviation from that path...even though subsequent paths will be faster, and well...better. The AR/M4, like it or not, has a reputation for being unreliable. Whether one particular AR has gone 150,000 rounds (like Chuck Taylor's Glock) is not relevant to the discussion. The reputation remains as much as that of the AK not being accurate. Just as attempts to make the AK more accurate are warranted, so are attempts to make the AR more reliable. One of those attempts has been the use of a Piston in lieu of the Direct Impingement. *The AR style rifle is and can be considered a piston operation: Piston definition from Merriam Webster Student Dictionary: Function: noun, : a sliding piece moved by or moving against the pressure of a fluid (as steam or hot gases) that usually consists of a short solid cylinder moving within a larger hollow cylinder.Piston definition Go to any forum where there are a higher number of DI makers advertising and the Piston AR is reviled as if it were the product of Lucifer himself. And of course, the only DI guns worthy of consideration are those sold by the advertising companies....who also happen to be on some arbitrary list. Yet go to a forum where Piston guns advertise more and DI is seen as some backward rifle akin to a crossbow. With the guns sold by the companies in question being the only choice. *The piston rifle itself was designed as a solution for a problem that never existed. Now is being looked at as the next best thing since sliced bread. Business is business and nobody can blame them. But I must say...after studying the matter thoroughly, the piston AR is an improvement over the Direct Impingement concept. Argue if you will but that is the conclusion I arrived at on the matter. I suspect this will create at least twelve pages of excoriation at one of those wannabe AR-15 forums. Well, I hope at least the get the URL correct. *A one person conclusion with no scientific data as back up or proof. In subsequent discussion we will discuss which guns are the best value and why (HK416 vs. LWRC vs. SIG516....for examples), as well as answer the detractions of the piston concept. DI Gun Advantages - 1). It will cost the buyer less money. I do not use the "C" word (cheap). That can be good or bad depending on what you get. A WASR 10 will also cost less money, but it is hardly anyone's first choice. A rotary dial phone will still work, but it hardly the best choice today. DI gun can be very good...but it is still a DI gun. *No information listed here, personal speculation. 2). Lighter recoil than Piston Guns (are we realy comparing the recoil of a 5.56!!??) *Recoil is recoil, take it for what it is, you don’t want to feel recoil… don’t shoot. 3). One thing you commonly hear is that it has commonly available parts. Well we need to qualify that. If you have the parts in your possession that is fine. if not, you will have to order them. Not being in a military role, that is what you will need to do anyway. So if you simply buy what you need beforehand, and have it available, it is really as much a non-issue as AK-magazine availability. *Again, no pertinent information listed here, personal speculation. (NOTE: Notice that there are only 3 “DI Gun Advantages” listed and yet none are actual advantages. Another way for the author to stack the article in his favor. Piston Gun Advantages - 1). Avoids the fouling and carbon build up common in DI guns. Fouling is the main cause of the AR's unreliable rep. Fix that and you have a new animal altogether. *Personal speculation. With proper care and maintenance, a DI rifle will run great. Something not covered or explained. Q: How does it “Avoid fouling and carbon build up”? A: It doesn’t. It just puts them in another location to clean. 2). Did you know that an M4 in service is intended to be rebuilt every few thousand rounds? The parts wear out. That is directly from a US Army M16 Armorer. A Piston gun, OTOH, does not heat the internals of the gun as much as DI guns. That means that the various small internal pieces and springs will not get subjected to the heat in a DI platform. That translates into far longer service life and enhanced reliability. *An educated person that can read a military TM (technical manual) would understand that. It is called Preventive Maintenance Checks and Services (PMCS). Parts have a tolerance of + or -. As long as it is within that range, it is functional. If it is out of that range, replace it. So it doesn’t translate into anything. Again with proper care and maintenance you can have a long life too. 3). In our in house testing, I have found the piston guns to cycle faster than the DI guns. Not a conclusive, split-time examining test, just a feel. On the DI guns you can feel the action working between shots. On a piston gun, it is press trigger, shot out. Perhaps we need to dwell in this area a bit more. *”In house” fancy for saying we took it outside and shot it No “conclusive” “just a feel” another way of saying he has a highly calibrated shoulder. Of course you can feel the action work on either rifle, just depends on how fast you pull the trigger. * No way to prove that the cycle of operation was faster on either rifle until you strip them down side by side and verify that the SAME amount of gas is doing the same work on both rifles. Meaning to check the gas port size in both barrels to ensure the same amount of gas is the same at the start. 4). Ease of maintenance is only overshadowed by ease of replacement. Carrying a spare anything with you is as easy as it is with a DI gun, but only easier to replace. *How would this be “ease of maintenance”? Let alone “ease of replacement”? Because there are more moving parts in the piston rifle than the DI rifle. 5). Finally, the piston gun keeps the blowback out of your face and nose and lungs. We hear all manner of dram from "second hand smoke" yet we hear nothing about the lung-full of gas the DI shooter gets everytime he touches off a shot. I wonder if the Piston Guns are..."healthier". *Healthier? We’re talking about combat shooting, shoot move and communicate. If you move god forbid you take a breath in and get that nasty stuff in your nose or mouth. Simple solution… DON’T SHOOT. One cannot have a discussion of the Piston M4 without the HK416 dropping in. I am not certain if it was first, but it certainly was the most marketed, and of course...it is a top choice among US Special Ops. Using an HK416 to kill Bin Ladin was a telling rebuttal to "piston dtractors". These guys...the Special Ops guys tasked with the mission could have anything they want as money is no object. Yet the gun they used, and use, is not a Direct Impingement Rifle. Ernst Mauch, at HK, was tasked with an improvement program for the M4 as far back as 2001 and one of the primary issues faced was the DI gas system. Rather than build a "faster horse", Mauch went with the proven successful piston system as is seen in the G36. In less than two years, including time wasted fighting a lawsuit by Colt. I find it amazing how often American companies, resting on their laurels, fail to innovate, and get legally upset when a disruptive company does what they should have done all along. *Notice that he mentions “improvement program” as far back as 2001. That is because they have not been able to solve the one problem that piston rifles have over DI rifles. And that is carrier tilt, resulting in bolt breakings at their weakest point. The advantages of the 416 over standard DI M4 are well documented in the various tests conducted. Those advantages are of course said to be inconsequential by HK's competitors. What would anyone expect them to say....that yes, the HK is better? Unlikely. *What advantages? What tests? And yes they are inconsequential by competitors as it was conducted by HK and stacked in their favor. So again, what scientific proof is there for back up? The issue with the HK is simply that Heckler & Koch was damaged in 1994 when the AWB took place and, rightly so, they saw the US Civilian market as too unstable to mess with. This has changed of course, and many companies came back after 2004, but not HK. Their standing in the civilian market is poor. But one has to mention the 416 in any discussion like this as it is the gun that other try to emulate. *It’s not that their standing in the civilian market is poor; it’s that the general civilian market can’t afford their line of rifles and goes with the least expensive thing they can get their hands on. Since he wouldn’t use the “C” word, I won’t either.

As everybody knows, there is and always be the debate or argument over DI (direct impingement) vs. piston rifles. Well the topic has been brought up again by Gabe Suarez. I have tried to put up my comments or arguments and they just have a tendency to go to the way side since I'm not one of his kool-aid drinkers, trying to brown nose him, or ride his johnson... So by the grace of GOD and with your permission, I am going to post his article and my arguments here to reach the better public to read. I understand this is just a point of view, rant, soap box, opinion, or what have you, and you know what they say about opinions too they are like assholes, everybody has one, and some of them really stink. Warrier Talk News Thanks for taking the time to at least look in and give it a glance

ArmaLite actually has a tech note that covers this and has pictures too... As you can see, the M15 and AR-10A Bolt Stops are similar in shape. However, the AR- 10A Bolt Stops are clearly marked AR-10A. And, if you look closely at the upper left portion of those two parts, you’ll see significant visual differences between the two. The AR-10B Bolt Stop is very different in shape than the other two. Note the relatively large flat angled surface near the top of the AR-10B Bolt Stop. [img width=810 height=439]http://i215.photobucket.com/albums/cc90/mrraley/firearms%20stuff/Magrelease_zps4a12b043.jpg Differences among the three Magazine Catches can be seen in the shape of the boss on the right end of each catch. (This is the boss that engages the cutout in the magazine body in order to retain the magazine in the lower receiver.) The M15 and AR-10B Magazine Catches are similar in design. However, the magazine catch boss on the M15 Magazine Catch has a chamfer on its lower side (shown in red above), whereas the AR-10B boss lacks that chamfer. The AR-10A Magazine Catch is easy to differentiate from the other two. Note that the boss on the right end of the AR-10A Magazine Catch is rounded on its outer end. ArmaLite Tech note 101
