Buffers for AR's

[biggotis06]

Do any of you fellas use any of the buffers on the market? Like Buffer Technologies, or the shock absorber thingie from Enedine. Just wondered if the 5.56 has enough oomph to even hurt the weapon to start with. I personally use the shock buff in my 45's, to supposedly stop the slide from hammering the frame. But i'm not convinced this happens in an AR. Any thoughts. Thanks!

The factory buffer was designed and improved over the years to serve the purpose perfectly.

These after market parts are for those people who just HAVE to customize their guns.

Thanks dfariswheel, that was kinda my thinkin. I've never heard of the military "upgrading" their guns with any of these gadgets. You'd think they might use something like that as much as some of those 16's get shot , if it were a problem. I would think as well they pretty much got the kinks worked out. Thanks and good shootin !

The only thing I would add is that AR carbines cycle more violently than AR's with full length barrels.

This is due to the location of the gas port which is closer to the action on the shorter carbine length barrel so it operates at subtantially higher pressure.

But even carbines ship without any special type of buffer.

i ran a lower yesterday in a service rifle match after my beloved Colt hiccupped, that had some sort of recoil buffer deal in it...

because it was designed to work with a larger gas port i only got bolt cycling completely about 30% of the time...

my snafu was the buffer tube unscrewing about 1 thread. the buffer retaining spring and pin came out and allowed the buffer to follow the bolt forward that in turn would interfere with the hammer. i didnt get any ignition and would have put me completely out of the running...

because i used a lower that i didnt start with, i was out of contention anyway but i got 138 more points than i would have otherwise. i ran out of time and had some rushed shots whose rounds didnt go where i thought i was pointing them...

Thank you guys for the input. I think i'll leave my M-4 stock in that department. If it fails me i'll be sure to reply !

What kind of carbine are you running, barrel length, and what's the buffer you have in there now?

I've got MGI's QCB system and thought about buying their buffer too. They have a good sales pitch here: http://www.mgimilitary.com/buffer.htm

But I have not purchased one.

They have video clips there.

"Just to illustrate the effectiveness of the new buffer, we shot a few videos during the testing. It was not until we arrived back in the shop that we realized just how much the muzzle rise was decreased. It is very obvious when you are shooting, but it is nothing short of AMAZING to see. Above are two videos we put together from this last time out. Each video shows a 20-round burst with the factory buffer, followed by a 20-round burst using the new MGI buffer. If you put your mouse pointer on the muzzle of the firearm, you will notice an amazing lack of rise, even under these complete magazine dumps!
Finally, a simple, drop-in unit that will reduce the rate of fire in your M16, M4, or AR15 without loosing reliability. This new mechanical (not hydraulic, like others) unit will automatically adjust to your individual weapon decreasing the rate of fire while increasing the accuracy potential. There are no special or weakened springs used with our system to interfere with feed reliability. Testing has shown rate of fire reduction of over 300 rounds per minute. Muzzle climb is drastically reduced meaning more rounds on your target. The faster your cyclic rate is, the more reduction you will see. During our testing, an 11.5" M16 with a cyclic rate of nearly 1100 rounds per minute was tamed by our buffer to function at 754 rounds per minute. We also tested the unit in an M16 with a 20" barrel that was cycling at 771 rounds per minute. It dropped to 585 rounds per minute with this new rate reducer and almost completely eliminated muzzle rise, even under full automatic fire!

Our new rate reducing buffer will function in both full length rifles and carbines. It has been tested with three calibers including 5.56mm, 9mm and 7.62x39, and functions well with all. "

Just to clarify, my LE6920 came with an "H" buffer.

Just to clarify, my LE6920 came with an "H" buffer.

I would not mess with it. That's the correct weight to run with USGI spec ammo and heavier tactical loads as well.
