I just bought a magpul ucs stock. It fits the look of the 556 compared to most stocks, and seems pretty sturdy. Would love to find a 556 folder lower for a good price. Until then ill rock this one.
Applied for form 1 and form 4 last Wednesday, got form 4 in 2 days and form 1 in 6 days. Sig 556 with dead air sierra 5
I got mine in today waiting for my form 4 to go through.
Anyone tried them out and does it help?
Just finished the 550 to 552 handguard conversion for the 556 with the JMac adapter. Im going to try to find the picatinny rails so I can drill those holes also.
