M4 Carbine Buffer/Spring Set Up

[RT13]

I have an AR Carbine with a 16" 1/7 twist barrel DI system with a full auto BCG. I just want to tame down the recoil and extraction a bit while improving reliability at the same time. What combo or parts do you guys recommend or use that works well? Been doing alot of research and reading on this subject but can't find a definite answer. Wolff extra power spring, H buffer, H2, H3, and Spikes ST-T2 all powdererd tungsten buffer weighing 4.3, oz similar to an H3 buffer weight at 4.5oz. I was thinking either just get a ST-T2 or combination of the H buffer with the Wolff buffer spring. Or too much? Seems like alot of AR carbines come with H buffers now, but mine had a standard one.

just my 2-cents but i like the st-2 buffer from spikes......

Do you have one? I was trying to find feedback if they even make a noticable difference for the extra $20 they cost over a standard mil-spec buffer.

I have one of those buffer-tech hydraulic ones that works like a shock, and for $80 i dont think its any better then the standard $10 one, plus I hear they wear out uber fast and leak oil.

It is all going to depend upon your rifle, and what ammo you typically shoot. Watch where your brass lands, optimally between 3 and 4 o'clock, if the barrel is 12 o'clock. Farther forward could use more weight in the carrier/buffer, farther back could use less weight in the carrier/buffer. For the best feel, and ultimately the least wear, tune yours for 3 o'clock. The hydraulic buffers from einedine work, and feel good, nearly the same as a good muzzle break, but without the muzzle blast for your neighbors. I personally like the Spikes ST-T2 as well, as I currently have it in a couple of my rifles. I believe AR15barrels.com posted a few graphs and pictures, depicting the differences includes weights. These are a good reference. Do a search here for him, and you will see some good info on buffer systems.

Buffer weight is dependant on the number of tungsten and steel weights in the buffer. An H3 carbine buffer has 3 tungsten weights inside whereas a standard buffer is simply 3 steel weights. A rifle buffer has 7 weights inside.

The gas system for each rifle should be tuned by the factory for each application...

I would recommend a JP adjustable gas block and fix the ammo you feed in it. Bear in mind the JP adj. gas block is not for life-or-death situations...I have set a system up for XM193 and then it would not cycle for commercial PMC 223 loads due to the lower pressure generated in that commerically loaded ammo...

I mostly shoot 55 gr fmj and occasional 62 gr or higher. My cartridges bounce off the deflector and mostly land at 3 o clock with a few going to 2 o clock area. The cartridges seem to fly far across over to the stall next to me and I feel bad for whoever is sitting there.

Here's one I found; the folks here speak highly of the ST-T2 and a poll was started with great results for it.

But also found this not so thrilling fact about the ST-T2.

for all the ammo i used including wolf, pmc, xm193, m855, etc, i used a bcm carbine spring and a bcm h2 buffer, reliable

I use this, DPMS heavy buffer with great results on both my 5.45x39 and the 5.56 carbines.

Has taken many many thousands of rounds with zero damage showing.
