I have someone sending me a RRA bolt, should have it next week. About 90% sure the bolt is the only modification.
I would say the uppers are going to be flat tops. I am not much of an AR guy; if you wanted the carry handle donít they make one that will mount onto a flat top?
All of LWD uppers (no ETA) will come threaded for suppressors. I am 99% sure we will offer SBR uppers as well. If you have a different upper, you can send us the bolt and have the modification done.
