D.R.D.

Very nice. Did you add a recoil lug? How do you like that stock?

Check out the Burris XTR II 4-20x50. I just got one with a Horus 59 reticle for under $1200. You can get it for under a grand with other reticles. SniperCentral, CS Tactical and others gave it a pretty good nod, and it's got a really durability record so far according to them (meaning , they hardly see them returned for servicing, unlike Vortex and others). Great warranty, Japanese glass I think, etc, etc.

Thanks. I appreciate your help. Got some other parts on order. so I'll keep you posted. Cheers

You're looking at the UTG. Regardless what they told you on the phone, you can plainly see it's 7 11/16" internal depth. The Vltor measured a tiny bit over 7 3/4"

The attached image is of the UTG Pro. I measured the Vltor side-by-side before putting it on, and it was only ~5/8" deeper. Both are very well lubed, as is the spring.

This is the one I ordered: Product #: 348370 https://www.midwayusa.com/product/348370/vltor-a5-recoil-system-carbine-receiver-extension-buffer-tube-7-position-mil-spec-diameter-ar-15-aluminum-black?utm_medium=email&utm_source=service&utm_campaign=order-confirmation&utm_content=product-description-link

So then, I guess I wondering if there is any risk to doing nay damage to the receiver or BCG if I put this: https://dsgarms.com/armec0040 with the H3 Buffer or this: https://www.kakindustry.com/lr308-carbine-buffer-heavy with the EA1095 spring or the shorter spring and .308 carbine buffer? ...all would be running in the Vltor A5 7 5/8" tube.

Alright, so I got the Vltor A5 extended (7 5/8") tube. It turned out it was only 1/8" longer than the UTG Pro I had on before. Now this is happening. It's not even ejecting. I even opened up the gas block all the way. No dice. Tried 5 different mags. Multiple settings withe the gas block too. No cycling. Considering the heavier buffer to slow the cycling, but I can't help feeling like even though the bolt can lock back, there's not enough room in that tube for the H3 buffer & EA1095 spring. So even if I put in the XH Carbine Buffer, it's still the same 3.250" as the H3. One additional things I noticed: If I insert a mag loaded with two rounds, chamber a round, then pull back the charging handle a 1/2" to check that the round was chambered, the next round won't fire - as if the bolt won't go all the way forward again and the firing pin doesn't connect with the primer. I simply hear a click. This whole thing is frustrating, especially since it's shooting sub MOA. Might as well have a bolt-gun at this point. LOL!

Er....why would anyone pay that when they are now shipping NEW for $87 until xmas? *Link removed*

I spoke with Clint at Heavy Buffers as well. He agrees with what 98Z5V wrote. Given the recoil of 168-178gr loads, and an effective break, I wouldn't want to go lighter than 5.4 oz. on that buffer. So, I ordered the Vltor extension. It will be in next week.

Ok, so here's what I've got. Bolt seems to go all the way back, mag & bolt catches engage properly when manually pulled back. Check out the gas tube position. External length of the tube is just shy of 8" Internal length seems to come in at 7 1/4" What about dropping in one of these: http://heavybuffers.com/car10xh.html Would I be able to use my Armalite spring, or have to use the Heavy Buffer's spring? Aren't there slightly shorter springs that I could use instead of the current one to solve the same issues?

This one? https://www.midwayusa.com/product/1003409554/vltor-a5-recoil-system-carbine-receiver-extension-buffer-tube-7-position-mil-spec-diameter-ar-15-aluminum-black I did in fact measure it when I first received it - but I only measured the exterior length, and compared it to a AR15 receiver extension tube. I didn't measure the internal depth. Figured I was good to go, especially when it seemed to lock back when built. What about dropping in one of these: http://heavybuffers.com/car10xh.html Would I be able to use my Armalite spring, or have to use the Heavy Buffer's spring?

Won't be able to get to this for a few days due to work...so don't eat all your popcorn just yet...

So, for best results with a rifle length gas system, how far should it protrude compared to the photo above?

Yeah, that wasn't my build, just a thread I responded to, I believe. It was a build idea, not my actual rifle. Matt, LOL - yeah, that damn LW. I only had to speak with them once, it was delivered on time, and shot less that a 3/4" group with the first 4 shots out of the tube. I should probably replace it.... ;-) 98ZV5 - I'll measure as soon as I can, then lube it silly, and try again with 3 different mags and let you know...

How far should it go?

I'll call leapers tomorrow, then take the buffer out and measure it

It is 7 5/8" I researched before I purchased it, then measured it. It was made specifically for .308. Yes, the bolt locks back, no problem.

Yes, the Armalite H3 buffer and the EA1095 spring in a UTG PRO tube: https://www.opticsplanet.com/leapers-utg-pro-6-position-mil-spec-extension-tube-for-308.html (Leaper's - I know, but the PRO series is made in the USA)

Bolt is not locking back. Following rounds are not being chambered Running Federal 168gr Gold Medal Match Ammo I began opening up the adjustable gas block incrementally. No change. Could this be a mag issue? I'm running PMAGs - feeding lips? How do I know? Could this be a bolt or mag catch issue? I'm using Fulton Armory LPK. Again how would I know? I had the bolt carrier, (D. Wilson Mfg) and the buffer/spring (Armalite) permanently dry lubed with slipstream, and put wet slipstream on top of that. The gun shoots like a laser, but just won't cycle. Only 25 rounds total, through it at this point (shoots sub 3/4" MOA :) What order should I consider the above? Other issues I'm over-looking? Thanks, DRD

Interesting: (from the comments below the article) "Ok you made the comment “surgeons can’t tell by looking at a cadaver on a slab which caliber put them there.” Two problems with that. 1 If it’s on a slab in a morgue it would be a pathologist or coroner looking at it. Any experienced of those could definitely tell the difference by the size of the entry/exit holes and surrounding tissue damage. That’s their job. 2. Having worked on many a poor soul in a trauma OR for almost 25 years, where surgeons do see the damage, I can say with a personal record of about 72% accuracy that just looking at x-rays I know whether it’s a 9mm or a 45acp. That goes up drastically once I see the actual wound. Even the high end expanding 9mm self defense round make small dime to nickel sized holes, unless they hit long bone, the bone is shattered and small pieces of the bullet are mixed in with the bone fragments. . The 40 makes nickel to quater sized holes long bones are also shattered and big pieces of bullet are present. The 45acp rounds make lemon sized holes, long bones are powdered and the mostly intact bullet is found past the bone not in its fragments. When it comes to vitals hit, heart, lungs, liver. Heart hits well all calibers the victim is gone by the time they reach us. Lung, 9mm unless it’s in the hylum no problem ewsy fix sew up the hole, 40 you’re missing a small chunk of lung to fix same with the hylum, 45acp well that lobe of the lung is a goner. Hylum hits 9mm if the Pulmonary artery and vein are not directly hit pain in the arse but fixable, 40 same, 45acp d.o.a. even a near miss shreds the P.A. and P.V. Now on to the liver. 9mm makes messy holes that are fillable with coagulants, 40 larger holes that require the use of lots of electrocautery as well as the coagulants, 45acp usually we have to resect that section of the liver to stop the bleeding due to that area is pretty much liquified. This has been my actual experience working in US Navy during Desert Storm and a level one trauma facility in Washington DC for more than 2 decades. We have a VERY active gun and knife club and the police, secret service and miltary police shoot lots of people with a combination of these rounds, the bad guys add even more. You see as many holes as I have you can easily tell the difference."
