RDSWriter 5 Posted April 9, 2013 Report Share Posted April 9, 2013 (edited) I am looking to sell an original (Halo) Monolithic Arms S12 quadrail forearm with integrated sights. This is much heavier than most products on the market and helps with muzzle rise. No longer produced... as the company was acquired. I installed it on my S12 and used if briefly, but decided to go another direction with wood furniture. The forearm only has slight wear where it was installed/contacted the 'trunion' of the S12. Asking $175. Please IM if interested. (thanks for the reminder on 'Halo' Cobra... I actually forgot that was the original name) Edited April 9, 2013 by RDSWriter Link to post Share on other sites
