Spike's Tactical ST-T1 Tungsten Buffer - 3 oz
Each ST-T1 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. The ST-T1 eliminates the chance of bolt bounce, helps with muzzle rise when firing in full-auto, and cuts down on felt recoil. It is a huge upgrade from a standard carbine buffer. While designed for .223 Rem/5.56 NATO, the ST-T1 works with all calibers. Get one for your AR-15 today and feel the difference!
Ratings & Reviews
More for Primary Arms than the product
by Brian -
I haven't had a chance to try it out just yet but it looks and feels like a quality product and it fit as expected. I purchased it with a carbine buffer spring, a small parts kit and an ambi sling point end plate. I did have some issues with the shipping company losing my package but Primary Arms was right on top of it making sure that I was taken care off so I highly recomend both this producct and Primary Arms. I've already come back to do more business with them.
Much better than PSA stock buffer!

So honestly I thought this was just gonna be a regular buffer but compared to what shipped with me PSA 300 blk pistol its like night and day. The one that came with the original rifle was a POS. This one is solid as a rock. Of course it isn't a necessity purchase but most of the things we buy aren't. Highly recommend the product.

The best buffer, period. Love it. Less noise and rattle is more pleasing than you think.

The Spikes buffer is yet another winner offered by Spikes Tactical. Super high quality, and very attractive as well. They just keep doing it right. This 3.0 oz. buffer is a perfect choice, teamed up with a mid length gas system, and adjustable gas block.

Spikes products live up to their reputation. This, and the polished buffer spring added a noticeable difference!
Quality AR15 buffer upgrade
by Rob K
Spike's ST-T1 buffer is a quality product and noticed the tungsten powder filled buffer with its sliky & quiet attributes compared to standard stock buffer with the internal weight moving within. Currently waiting on JP Enterprises AR15 performance buffer spring to complete the upgrade and pending range field test and reason for 4-star rating at this time.
