Give this a look. It filled with tungsten powder. Quiet and smooth for not a lot of money.
Spike's Tactical ST-T2 Tungsten Heavy Buffer - 4.0oz
Thanks. Ordered it. Came in today. I got the whole kit. Buffer tube, spring, buffer, etc.
Much to my surprise, when I looked at my 6933 SBR, it had an "H" buffer. I would have expected H2. This explains the brass marks on the deflector. This is my duty, CQB, and HD rifle. While I admit to being "Queer for Colt", I upgraded with a 6933 EPR upper (I have two of them now); Aimpoint Comp M4S optic; Magpul metal BUS; Raptor CH; and TLR-1HL lights, on both of the uppers. The 6933 lower sports a Geisselle e-SSA trigger; Hogue grip; and Magpul MS-1 two point sling. I run Hornady 75 TAP SBR in this gun, and I am dialed in on a 50/200 (MPBR) zero. The gun is much better than the shooter, but I made a pass through a 180 degree "kill house" with it a few months back, and at 59 years old, I ran (just) under time and went 12/12 on "shoot" targets, including two headshots on hostage-holder targets. Not bad for an old white guy.
A co-worker who has forgotten more about the AR-15 platform than I will ever know, and who does all of my gun work, suggested I look at an aftermarket buffer system after he shot it. He, too, suggested the Spikes. I threw it out here to see what I got. So I went with Spikes, and he will install it tomorrow afternoon. Also going to do a minor tweak to my thermal 6721. As soon as that buffer system is in, we are going to go shoot it to confirm operation. He tells me I'll be pleased. I've seen enough of his work to already know he's right.
So, thanks. Funny, this all started with GV...how many years ago now, GV?...and now I am at a point where I am comfortable engaging from point blank to roughly 200 yards...inside or out...night or day...and whether you're moving or not. All I have to do is pick the right platform.
And yes, in true "GV fashion", I have enough ammo to fight a small war.
Go Vols.
