6.8 spc build


The buffer assembly came with Spike tactical's T2 buffer, Spring, and buffer tube. Spike technicals T2 bufferbis about $38, the complete buffer assembly was only $69. Good deal.

Great quality

Spikes Tactical Buffer tube assembly


Amazing. Will always do business with Primary Arms.



As always spikes has high quality affordable products!

Quality Worth the Extra Coin


As soon as you see this set up you know where the extra money went. The tube is solid with a nice finish. The spring is nice and thick. But the buffer is what takes the cake. Nice solid design and filled with a powder vs metal weights like other buffers. Makes for a much nicer cycle you can definitely feel the difference right away. Also buffer has the Spikes logo on it for a bit of cool factor. But for my 7.62x39 this heavy buffer made all the difference. If your Goin to put money into a rifle why go cheap? Get quality parts. And these definitely are quality parts. Thanks again to Primary Arms for their fast shipping.

Solid Kit


Awesome Kit! Super Easy to install! Love the slightly heavier Buffer!

Top notch


BCG is in great condition abd properly staked.



Bought for my Spikes lower very good quality and I liked the ST-T2 buffer so much I ordered a few more for my other rifles

As Promised


Buffer tube showed up quick and as expected. I have not installed yet so can't give any more of a review other than so far so good.... 4 stars only as nothing is perfect and you must always strive to be/do better
