Heavy buffer?
« on: December 31, 2010, 09:57:57 PM »

Howdy rabble,

I've yet to pin the upper to my lower, so I have no idea how the 458 will cycle with my rifle. I have a bit of time before it arrives, and a strong itch to learn.

Should I consider a heavy buffer? I'm set up with a rifle length tube now, and a nice weighty Magpul PRS.

TIA.

Kevin

Heavy buffer is not needed.  The SOCOM was designed to work with a standard buffer and spring.

I have the same set up R/L tube and Magpul PRS.  I installed a Tubb CS buffer spring and use a standard buffer.  My rifle is 100% reliable and is not harsh in recoil.

Agreed, heavy buffer not needed, but it will cut down on the recoil, at least the sharpness of the impulse.

I tried both a H2 and an H buffer and it would occasionally fail to feed. I believe the bolt was not moving far enough rearward to grab the next round off the mag and would close without the round.

Put the standard buffer back in and has worked 100%.

This was on my 12" SBR with a pistol length gas system.

May just have been your rifle. I have one of Slash's XD buffers made for the .458 SOCOM pushing a carbine length spring and it is working 100%.

Mine uses a Spikes ST-T2 on a regular carbine spring with my Magpul CTR, No issues (unless I use the 3 pieces of brass with the collapsed shoulder) :(

I'm running a standard buffer with the RRA heavy duty carbine length spring - no issues.

Standard buffer that came with the A2 stock. I have the two that came from RRA, I've had no need to try them.

I use an H buffer in my CavArms lower because they told me to!

It works well!

I use a MGI buffer with a carbine tube and stock spring.  It weighs about the same as a rifle buffer, ~5.2 oz. and works great for me.

I am using a Slash H SS buffer with red spring from RRA in mine only because that is the only buffer I had laying around


it was in my POF 416 and that one now has one of his no tilt buffers in it

my RRA upper has shot fine with my loads of Hornady 325 grain FTX with 36 gr of H110

cycled correctly every time
but seems to have some marks on the case head

not sure if this is a buffer problem

didn't need to trim after one shooting

Slash's HSS buffer is 6.2 ounces. I have his XH buffer (which Slash says he made for the Cavalry Arms lower with a .458 SOCOM upper) that is 8.0 ounces and mine works just fine.

I tried a HB in my first .458 SOCOM, 16 inch, CAR gas, back when it wore a CAR length stock.  It turned a perfectly reliable rifle into a jam-o-matic.  Putting back in the standard CAR buffer returned the rifle to perfect performance again.  However, I no longer run any CAR length stocks on my .458S ARs because the longer rifle length stocks fit me better.  Now I run standard rifle buffers in all three of my AR .458 SOCOMs.  The 16 inch and the 12.5 inch wear the ACE M4 SOCOM Long (fixed into position) which uses standard rifle buffers and springs and they work perfectly, as does the A2 length woody 20 inch with midlength gas.
