300 BLK Build

[colton barnes]

I just did my paperwork for a TBAC 30 P1. So now I am gonna build a 300 blk as one of it's host's. I have DPMS lower with an AR Fx stock, rifle length buffer tube with a cyclic rate reducer buffer.

I want a 16 upper that will cycle all loads. Suppressed super and subs, and un-suppresed superes. Any suggestions on a good upper. I would like to avoid some of the cycle issues I have read about.

Do I need to get a new buffer? If so which buffer do I need for I rifle length tube?

Thanks for your help. I'm new around here.

I run an H2 with a Wolff extra power recoil spring in my Noveske. I can find 98% of my brass with thi set up.
