It was a test for you. lol No just kidding. I'm aware the technical name for the buffer tube is receiver extension but I haven used that term in a long time and I had a temporary brain fart. However I will say about your statement, The 7" is a nominal value in my opinion. Id say we all agree that 7" ID should be the minimum length, more often than now I measure actually 7 1/8" - 7 3/16" for this nominal 7" 308 buffer however, just to be sure we are all on the same page, this does not address the few buffer tubes (receiver extensions) that are specifically designed to be longer set ups and measure longer than 7" ID but still under 8" for certain specific set ups. If you dont mention this, someone will measure their tube to be a bit longer and throw it in the trash also because it doesn't measure within that 7"-7 3/16" range

yep agreed, not withstanding differences between AR-15's and AR-308's

when you guys say 7" extensions?? what does that mean, do you mean 7" buffer tube or? His tube now is only an 1/8" or so short, are you advocating some sort of extension of a whole new tube/ never heard of an extension for a short tube.

Thats a fair statement

Explain please

Thank you for your courtesy, much appreciated by all,

I see a number of guys discussing boat tail, hollow points, etc. Isn't it true that some have issues running these through an AR semi-auto platform? Of course all of them run through bolt guns but just curious about this. Also what would you say is the best balance of power/stability, and ideal ballistic characteristics in the different bullet weights available, from a low of say 110 grain all the way up given a 308/7.62 round, 24" barrel length. An then finally getting back to my original post, if I were looking for an extremely accurate round for long range application, but that also had high potential for a hit that would cause maximum damage to flesh but at the same time penetrate armored or hard targets as more of a do all round, what would it be? I know this is a tough question and is subjective, just trying to get a consensus.

how about some other examples of a more traditional projectile weight. That's pretty lite for some guns and doesn't run well depending on Barrel twist and setup. any other examples of more traditional bullet weight that you guys have also found to be extremely accurate and is this also further dependent upon whether the weapon is a bolt-action or an AR platform type weapon just curious?

Copy that. Thank you

Gotcha, my scope is a very new one with a 56mm objective. And guys rave about the rings that come with it as being really substantial and heavy BUT, I dont know what size or height they are. I will tell you this though, when its mounted with the factory rings, the scope barely clears the rail at the objevctive lense. But your information is very helpful

I see how this works, I understand thank you. One question, how does the set up compensate for raising the scope this much? of for that matter, any of these extending devices that mount on top of the existing receiver rail? I know its not much but it seems like that little bit would make a lot of difference in the scope adjustment and the range of elevation left on the scope after raising it? mike

Ok gotcha. Much appreciated

what makes it acceptable with this mk12 but not the ar 308? what makes it different

Well these are 35mm rings so I'm not sure if they even make extenders for that. Also I never thought about the issue of Bridging the handguard and receiver but that does seem to be a valid concern. I suppose you are saying that the traditional wisdom is that the scope should always be fully mounted on the receiver as opposed to fully mounted on the handguard and certainly might not mounted on both. Is that more or less what you were saying

tell me more please

Will do buddy

Thanks for all the help. I remain very confused but at least I'm making a change to see if it works. The link provided to me for dpms shows the rifle buffer being short and only weighing like 3.2 oz? However slash and 98z5v both say the buffer should be 5.2 long??? Also the buffer slash says is right for me weighs 10oz and that is 3 times what the dpms one supposedly is.

No . I bought only the stock. The spring and buffer were sourced separately. I've been in communication with Slash and I think I have everything figured out in terms of what it will take to make it run properly I am going to order from him a new spring and buffer that should solve the problem and apparently the one I am using is a bit too long the buffer, and the spring is apparently a bit too weak so I will be ordering the stuff and running the gun again to see what kind of improvements have been made and report back. Thanks much to all

Not sure where I got the buffer. Trying to find receipts for it now and have not been able to yet. As far as the stock, wouldn't it only matter about the tube and not what stock was on it?

Ok I get it. I guess I was just thinking it would be really valuable to compare pros and cons of all the popular barrel types. Thanks for the great info

Let's agree to disagree buddy and call that one over. I do respect your opinion though. On the issue of the buffer. You say I have an ar15 rifle buffer in there? Please help.me understand your point and what you think it SHOULD have and please be specific. Keep in mind, the buffer is 6.2 oz. Have you seen an ar15 rifle buffer that heavy before? Mike

Very informative thank you. But, if we are covering these, why not throw into the mix stainless barrels, I think many of us would be interested in that comparison also.

I must say, I am rather partial to it myself. lol

Ok,. I'm hoping this post clears up a lot of questions for you and for me. ISSUE #1 My buffer upon remeasuring it is 5.91" long. It weighs exactly 6.2 oz. This buffer was advertised as being for a ,308 and was also advertised as being 5.5 oz which obviously it is not. The buffer tube is exactly 9.75" inside dimension. The buffer spring is a stainless spring, 12.5" long relaxed, with 29-30 coils. If it would help to measure the wire size, I'd be happy to do that. ISSUE #2 Magazine catch/release button assembly. 98Z5V DEWS. I'm not trying to be adversarial and I very much appreciate your help but... There is a known issue with Aero lower receivers in the 308 and possibly the AR-15 5.56 as well although I have no experience with that. A normal size stud will NOT be long enough to engage properly with sufficient thread engagement a normal size release button. This can be resolved one of two ways, the Aero lower parts kit includes a longer than normal button which seats deeper into the receiver to work with the standard size button release stud. OR another way to solve it is to use a standard size button release with a LONGER stud sold by KAK as an example which ALSO works. This information has been verified by speaking with the tech support folks at Aero and you can verify this yourself by calling or emailing them. I do agree though, this is a little know issue by many people and it took me a while to understand what was going on and ultimately a phone call to them, Please continue to help with the buffer issue though, I do appreciate it. mike

Well to make maters even more interesting, I just weighed by buffer on a professional scale and it weighs in at 6.2 oz. What odd is that when I bought it, it was advertised as weighing 5.5oz
