Which buffer for 7.62x39 ar

Subjectively I didn't notice that much difference between them, if any, all configurations worked. I wound up putting mine on a lower with an A2 rifle stock and that is my preferred setup for it at the moment, as it does seem noticeably smoother. I was mainly trying to correct an issue with my mags not bringing up rounds fast enough and wanted to slow things down, but it also smoothed out the recoil impulse quite a bit.

So it's really just personal preference, didn't have any issues running any ammo including Tula. But I did try a Wolff xtra power buffer spring to fix another problem and that setup with the heavy buffer wouldn't cycle Tula reliably.

I even tried it again after hitting the 3k round mark just to make sure everything had worn in, same results. Bear or surplus Yugo M67 anyways. I use a regular carbine spring and an H buffer. Ran 60 rounds through it and the shells all wound up in a 2' circle, 8' away at 4 o'clock. I'm very happy with my inexpensive home assembled 7. My buddy who was spotting for me also shot it and said he hadn't had that much fun at the range in awhile.

He harrased me about it the whole time I was collecting parts and putting it together. Had to eat those words! Quick Navigation Beyond 5. Bookmarks Bookmarks del. As long as you maintain reliability of extraction, feeding and last round bho, I don't see any reason to not use as heavy buffers as possible.

Edit; In my 7. Quoted: I am currently running a 16" Hardened Arms upper with carbine length gas and a standard buffer tube with a carbine I weighed it at 2. As for heavier buffers reducing the felt recoil that is somewhat subjective with the shooter. I really could not discern that much difference between the carbine and either a H2 or H3 buffer in my 16 inch PSA 7.

To me, my 7. I've always run a 9mm or H3 buffer in my 7. Heavier buffer slows your action down just a bit, giving the mag time to bring up the next round. And slightly smooth out the felt recoil pulse. So if you want to 'tune' your buffer this is the cheapest way. There's also a kit someone posted recently that was all the parts to make a std.

Quote History. Quoted: I've always run a 9mm or H3 buffer in my 7. People will often advise you to run the heaviest buffer that will function reliably. I disagree. Just don't. Carbine Buffer — 3 oz. For a carbine-length rifle, 3 oz. Heavy H Buffer — 3. There is a wide range of heavy buffers available, starting with the 3.

H2 Buffer — 4. If you fire 5. H3 Buffer — 5. If your AR platform fires 7. Pistol Buffer — 5. You would think a pistol caliber build, which uses smaller rounds overall, would require a lighter buffer weight. The opposite is true, though. In a pistol caliber build, the traditional gas system of an AR is missing outright.

Furthermore, the bolt carrier group is typically heavier. To smooth the action and ensure reliability, a larger buffer weight is a must-have. Specialty Buffer Weights Of course, for those of us who are extra-neurotic about peak performance, there are also even more specialized buffer systems. Spike's Intermediate Weights Looking to tune even more precisely? Geissele Super 42 Designed for DEVGRU to have extremely long-lasting springs, these braided wires also eleminate the "twang" sound some complain about from stock buffer springs.

JP Silent Capture JP offers a self-contained buffer system targeted towards competition shooters, allowing you to tune for your specific rifle. Sprinco Springs No article on buffers would be complete without including Sprinco, out of Texas. While they don't make buffer weights, their buffer springs are the OGs on the buffer world. They were truly the first to start altering weights, and their springs are some of the longest lasting available.
