Im looking into building an AR pistol in the near future and im wondering who makes the best, and the smallest AR pistol buffer tube / receiver extension? Ofcourse obviously reliability is my first concern, but i would also like to have it as short as possible.
Thanks

The GSE buffers are exactly what im looking for. Another quick question regarding the GSE buffers, can they be used with a normal bolt, or do they need a proprietary bolt?
