Another nice write up AT! BCG/buffer mass is a question for many of us and trial and error is the best answer. Maybe we should all list combos that work well for us so I'll start:

Daniel Defense 16" LW midlength with A2 flash hider, DD M16 BCG and BCM H buffer/spring. No shortstroking with Wolf.
ArmaLite 16" HBar midlength with A2 flash hider, ArmaLite AR-15 BCG and BCM H2 buffer/spring. No shortstroking with Wolf.


Since the ArmaLite has the AR-15 carrier that weighs about 0.5 oz less than the M16/FA, I jumped on the H2 buffer over the H as a test and it seems to be the sweet spot. I've tried the H2 in the DD and do shortstroke occasionally with Wolf so it's too much weight. I suspect the Spikes ST-T2 would function since its weight is between the H and H2 but haven't bothered.

Again, neither of mine have a comp, just the standard flash hider, I'm one of those old timers at the range, MJ mentioned.
Does a comp affect how the buffer functions as far as stroking / shell ejection?

Without any research in the matter, I'm going to say no real significant change for most muzzle devices. My reasoning is this: any muzzle device is going to add a little effective length to the barrel weather it be 1/8" or 1/2" not really a significant increase.

The easiest thing to do is look at the MD your are considering. Look for the ports/slots where gas can vent out. Shouldn't be too far from the bore.

Notable exceptions are Linear Brakes / Conical Compensator type MDs like the Troy Claymore or Noveske KX3. Tho unquantifiable by conventional means, they do add significantly increase dwell time. Remember, dwell time is the time the exhaust has to cycle the system. It begins when the bullet passes the gas port allowing the exhaust to go through the gas block, down the tube and push the gas key and bcg back. It ends when the bullet exits the bore and the exhaust has vents out the bore following the path of least resistance. Lengthening the barrel allows the gas to have more time to drive the system.

My people use them (including myself) on pistols and SBRs to increase the effective barrel length so the gas system has enough time and pressure to cycle completely. Think of them like mini supressors, which infact they are.

My thought on the issue is: Start with your BCG. Since last few years I have only fired AR's I built, currently I begin with a BCM BCG, and a MOE buttstock assembly , and a JP adjustable gas block with regard to name brand parts. I find it is easier to adjust the gas to the ammo than fool with the buffer weights. The recoil on an AR is really negligible and nothing you can do will really be a felt impact on it unless you are fortunate enough to own a NFA registered full auto. My beleif is you should focus on performance and reliability of your rifle, and leave the timing alone. Again, just my .02.

I have one on a BCM 16" Midlength and love it. It's not a comp though.

It's a nice looking design and works well, you won't be disappointed! They say it doesn't need to be timed but I did time it so one set of holes is at 12oclock. This puts a flat (no holes) at 6oclock like an A2 flash hider and I think would maximize the compensation effect.



Bottom is the DD Superior Suppressor and the top one is a Rainier Xtreme Tactial Comp
