Spike's Tactical ST-T2 Tungsten Heavy Buffer - 4.0oz
Each buffer is filled with high density tungsten powder and topped off with a MIL-SPEC bumper. Because of this, there aren’t any reciprocating weights inside to make a lot of noise and it also makes for a very smooth cycling rifle.
This 3.25" buffer is compatible with AR-15 MIL-SPEC and Commercial spec receiver extensions or 8" GI-spec AR-10/AR-308 receiver extensions.
Ratings & Reviews
Ive had the buffer for a few months now it does exactly what they say it does quiet and smooth, in the carbine rifle helps with feeding and recoil. Well worth the purchase. just bought #2 stt2 buffer 12/20/14
Great Buffer & Great Service from Primary Arms
All my AR's have Spikes Buffers. They are a well made high quality component that has never let me down. The customer service from Primary Arms is what other companies aspire to have. Always a fast shipper; order always correct; completely first class.
Great buffer upgrade - Spikes ST-T2
by Devry Sommer
All my carbines have these now. My M&P 15 I used for an AR 15 class, and performed flawlessly. I think they are a great upgrade, and Primary Arms is the best place to buy them, and least expensive. Thanks Primary Arms. Don't forget to LIKE them on Facebook.
Along with the Sprinco M-4 Carbine Extra Power Buffer Spring (Red), I have this ST-T2 buffer installed in my 6.5 Grendel.Both items really helped reduce the recoil of the said rifle.

Holy Smokes, it's quiet!
by Jon Eppler
Amazing how this buffer helps to quiet the "clanking" down. I paired it up with a David Tubbs flat wire buffer spring and now my wife loves to shoot my rifle. It even quietened her down. Delivery was super fast.
awesome product at a great price. These guys at primary arms are no joke, great customer service 24/7.

Bought this to replace a cheap buffer for my wife's AR. Great buffer, no problems at all. As usual, Primary Arms shipped supper quick.
Bought to go in an AR pistol build. Great finish, and weight should be just about right.This thing is quiet with tungsten powder inside instead of steel weights. As usual, PA was on point with shipping during the Holiday rush. Thanks PA !!

Can't beat the price, other than that, its a buffer, how much "better" can one be over an other?

Does what it supposed to do. Nothing fancy, but it works. Kind of hard to get excited over a buffer lol.

Every time I order from Primary I am astounded by the extremely fast service I receive! The items I order are also of top shelf quality! Usually, I receive my orders within 2 to 3 days, with one time being 4 but, that was the PO's fault!
Excellent price on a great product.
