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.

Great product. Had a stock PSA buffer that I replaced with this buffer. High quality and no rattles at all! Love how its marked on the outside as well so you can switch buffers quickly. If you have the money for it get one!
Great product! Highly recommend

I recently had a hydraulic buffer and had issues, so I of course started looking for a new buffer. I fell upon the spikes tactical buffer. Once installed no issues with cycling or recoil, very easy to install very happy with the performance. Would recommend to others to buy. Product was of very good quality.
Works well to reduce felt recoil
by DN -
Took the advice of the reviewer below me and paired the ST T2 with a JP Tuned spring and it noticeably reduced the snappy recoil in my ar pistol. I initially wanted to reduce the sharp recoil, but not quite an over gassed system and decided to go with the buffer + spring instead of an adjustable gas block. I had a small concern that my ar would not run low pressured ammo with the combination, but the bolt locks back every time and brass is ejected around 3:30 to 4 o'clock.
<br>Originally used the provided carbine buffer + milspec spring from KAK.
<br>I'm currently running a KAK brace kit, ST T2 and JP tuned spring, 11.3" barrel with a pinned gas block from BA. I shot PMC bronze .223 and AE .223.
This Buffer and a JP Tuned Spring changed my Life
by JBar -
I was having a lot of recoil knocking me off target, especically in rapid succession. I was having misfires with the TulAmmo I was feeding it and the bolt was not setting as strong as I liked. With this buffer and a JP Tuned spring, recoil is virtually gone, sighting is far more improved, misfires gone and bolt sets strong. I love it. It is like night and day. No more sore shoulder after 100's of rounds through it. Also FedEx is the way to go. UPS lost my buffer and John from customer service got me replaced and Fedex delivered my box undamaged. Their customer service is top notch. I would recommend this for sure!
Very effective upgrade!
I just received this buffer last week and shot my gun with it for the first time. Wow, what a difference from the carbine buffer, very pleased. The recoil is softer, the muzzle jump is less and it slows down the cyclic rate, which is a good thing. This is worth every penny great price!
This buffer is awesome!
I just shot my AR for the first time with this buffer and there is a definite difference from the carbine buffer. Its very quiet and I have less muzzle bounce. It just seem to recoil smoother, no "thunk". I'm very happy with this purchase.
Top notch buffer
Top notch buffer. Looks cool, no rattle, fit and finish are superb. Great upgrade. Used on a 16" mid length .223 build.
SPIKE TACTICAL ST-T2 BUFFER IS A CHEAP UPGRADE OVER STOCK BUFFER
Bought this all together with the Lantec UAR Billet Upper and Strike Industries Enhanced Forward Assist from Primary Arms. Spike ST-T2 buffer is pretty quiet with my Damage Industries Enhanced Buffer Spring. A perfect combination with my Magpul UBR Stock that I also bought from Primary Arms just a few month ago.
cant go wrong with spike heavy buffer
pick this up from primary arm to top off my damage industries enhanced buffer spring
Excellent Low-Cost Upgrade
Helps keep you on target between shots. Primary Arms was the only one in-stock at the time! Two thumbs up!
Smoother and Gentler
The powder fill is less "clackity" than my original buffer's chunks-o-metal. At 4oz it also mildly reduced recoil on my 16" middy. The really awesome part is that the gun will still shoot anything from cheapo Tula on up.
Great Product-Fast Shipping
Does have a five star rating for nothing. Product shipped quickly and was exactly as advertised. Would highly recommend to anyone.
Buffer fit perfect no problem's at all better than what came with my AR rifle. Primary Arms are the greatest and the shipping is outstanding fast and I plan to give them more of my business.
Super Fast Shipping Great Product

Too good to pass up.
by Hal Bass
I have this buffer in all of my EBRs and have bought them all from Primary Arms. The sale price on these last two was too good to pass up. Now I need two more lowers.Great delivery time, as usual.

works fantastic, I like the black and the spider logo on it. And again you can't beat the speed of delivery. Primary Arms is 2nd to none.
