Steel RDIAS Manufactured by Broadhead Armory in Michigan. Includes a few other full-auto parts from my abandoned M4 build. INCLUDED free with the sale are: Geissele SSF trigger -- new, installed but never fired, no package. Replacement Trip -- a machinist friend was in the process of making this from precipitation-hardened stainless 17-4 steel. The rough cut is almost finished, and it will need final fitting and final heat treat. The included original sear is fully functional also. Disconnector, Colt Mfg. -- in opened package, new unused. Full-Auto Selector Switch, Colt Mfg. -- new unused, no package. Form Card (not pictured) -- thermosensitive plastic (search Form Card), may help with final shimming to your receiver. TERMS Full payment up-front. Sorry not flexible on price, no trades, no discounts, no credit cards. A Colorado FFL/SOT3 (To Bear Arms, LLC) will have possession of the RDIAS in either Form 4 (current) or Form 3 status. You or your FFL may confirm this with them before sending money. I will pay one $200 transfer fee to the Colorado FFL. I will also pay for shipping by any common carrier that the buyer chooses, however shipping insurance costs and responsibility for the final package delivery are the buyer's.
