WTS Yankee Hill Lightweight Free Float and BUIS (Front and Rear).
USPS MO $175 delivered (one free float forearm, includes mounts and the front finishing end cap, and one set of BUIS). Would be a good candidate for SBR for suppressor underneath
have two just alike. These were mounted on an AR22, but never used in the field. One is still in safe on unfired TacSol AR22 upper.
