hey there guys! this is going to be my first ar build in a 5.56 and I was wondering is there any specific buffer tube system that designated for this caliber. im running a spikes tactical upper/ lower .
please shine some light on this for me. I was considering the spikes tactical st-t2 buffer system? any ideas? please help. |

I read forums where they mention the different weighted buffers. I wanted to go the Spike's Carbine Buffer Assembly Kit.
. kit includes Mil-Spec Buffer tube with dry film lube • Latch plate • Castle nut •Mil-Spec 17-7 Stainless Buffer spring • ST-T2 buffer will this system work ? |

Quoted:
what the difference between commercial and mil spec buffer tubes? Primarily, commercial tubes are made of cheaper aluminum, use cut threads instead of rolled threads, and are thicker, meaning mil-spec diameter stock bodies won't fit them. Even receiver extensions which are advertised as "milspec" usually aren't, they're just milspec diameter, but still made of cheaper material and with cut threads. There's no real functional difference, so if you buy the stock body and receiver extension as one unit, you won't need to worry about it. |
