Good day.

Spike's Tactical ST-T2 Heavy Buffer.
Anyone get a chance to try one of these yet?
If so, notice any difference compared to the standard buffer in a carbine?
I would imagine this would be effective in a CQB. (10.5" barrel)

Here's the manufacture quotes:

..filled with HDTP "High Density Tungsten Powder" so there is No reciprocating weights inside to make a lot of noise.
It also makes for a Very Smooth cycling rifle.
It eliminates the chance of bolt bounce and muzzle rise in (full-auto)......not applicable to CGN'ers.
It also cuts down on Felt Recoil.
It's a HUGE upgrade from a Standard Carbine buffer!
It's designed for .223/5.56 but it works in all Calibers!

Fab Sport and Questar should both carry this product...

In terms of use in a shorter barreled AR, I am not sure, but curious to see what others have to say about it!
 
I just installed one into my AR this afternoon (from Questar)...haven't had a chance to try it out yet. It is noticeably quieter than the standard buffer it replaced (but to be fair never noticed the noise to begin with). Looks pretty cool and feels like a quality piece though...
 
I installed one in a Tactical Innovations Lower I just finished assembling. I haven't completed the upper yet, but I slapped it on a buddies Colt 14.5" upper and it worked just fine. To be honest I didn't notice any noise with my ear protection on and the combustion of the gun powder :)

There is no wonder buffer out there, you use the heaviest buffer your rifle will cycle reliably with, be it H,H2,9mm,or the Spikes. There is no such thing as an instant upgrade for all rifles. You have to test different weights and figure out if the buffer weight works in your rifle,99% of the time it will be the one that shipped with your rifle.

Sure, because the muzzle blast is so quiet the noise from the buffer will give away your position.

If your carbine ejects somewhere between 3:00 and 4:30, you're already good. If it ejects forward of that a heavier buffer may be a good thing. If it ejects behind that, a heavier buffer may make things worse.
 
I ran a buffer weight experiment on my 11.5" AR a while back and the results were quite surprising.

I started with the standard 85g buffer and went all the way up to 304g which is a 260% weight increase. And the rifle runs just fine with all the extra buffer weight. It locks back on the last round every time and has never yet failed to feed or eject.

All of which lead me to the conclusion that a typical AR rifle is grossly over gassed.

If I were starting from scratch with a rifle I'd go with a 9mm buffer at the least.

i'm sure there's some truth to that. Also, the gas system is self-adjusting. If your carrier/buffer is light, it moves quickly and exposes the holes in the carrier quickly, dumping the excess gas. If everything is heavier, the holes are exposed more slowly and relatively more of the gas impulse is used.

Saputin, what size is the gas port on your 11.5? Are you sure it's typical?

I can say this, in my new guns, various lengths, lighter pressure ammo (by that I mean the pallet of 2006 Remington 55gn FMJ I'm working through, surprisingly accurate, but light pressure) won't always hold open on an empty mag with a H2 buffer, (feeds and ejects fine). The H2 smooths the recoil very noticeably with Mk262 ammo, definitely better operation vs standard buffer which rocks the gun. The 06 Remington works ok with a H buffer, Winchester 223R1 will hold back the H2 100% almost always.

I've really never had an experience that clashed with the general 'adjust buffer to ammo supply' advice. I generally run with an H in, if I can run an H2, I do.

So, my take on H2 buffers in general, nice addition when shooting high pressure ammo, but a possible negative when shooting lighter pressure ammunition.

I'm pretty sure my bolt wouldn't hold back with a pistol buffer on anything but the high pressure stuff.

For what it's worth, I do recommend H buffers in a carbine when customers ask, (or an H2 if they want), for smoother cycling if for nothing else. It's a nice upgrade.

I know Saputin knows, but don't know if everyone knows so, Heavy (H) and then Extra Heavy (H2) M4 carbine buffers were developed to slow the cyclic rate of fire in full automatic. For semi-auto, the extra reciprocal mass results in slower action speed, and less 'pulse' to the felt recoil. It can also help with operation on barrels with heavily eroded gas ports (ahem?).

I hope the milspec heavy buffers we sell aren't too loud in motion? Kidding, but there's a whole lotta stuff happening while that buffers moving around, and I'm wearing muffs. Some sensitive hearing. :D
 
Not to hijack but while we're on Spikes products does anyone own one of their SST-15s? And if so could you post some detailed photos? How is the fit and finish?
