Good color
by jj -
Works great in my 9mm build. Functions as expected. This buffer is standard length, so you may need to put a spacer behind the spring with a 9mm bolt. If the bolt travels more than 1/4in behind the bolt catch you need to add quarters behind the spring to take up the extra room.
As with many gun parts, feels a little overpriced.
Rattles
by Ronald -
the sliding weights move back and forth within the buffer. This causes and annoying rattle in an otherwise tight rifle. Functions as promised. But the rifle is noisy when carrying
Very nice

Fixed my LRBHO function on my PSA Glock compatible lower.
Another Great Product
by Timothy -
Spikes has done it again. Another great product. I bought this to use in a DPMS LR308, that repeatedly malfunctioned, due to over gassing. I installed this buffer and no more malfunctioning. I then bought a second one for another .308 AR that had the same problem. Cured both of them. You will need a .308 length tube, to use this in a 308.
Solved my cycling problems
by Leland Palmer
Was having cycling problems with a friend's .300 BO 18" carbine. This buffer solved it. It's Spikes so you know it's good stuff.
Works for my suppressed setup
by James Dodd
Got this for my suppressed AR (16" mid-length barrel) that would not run correctly with the A2 stock (rifle buffer) system. Got a spikes spacer as well as a carbine spring and this T3 buffer and it runs like it was designed that way. Couldn't be happier.
