Lapco OD / olive green back bottle asa in used shape off old so cal rentals. Has tiny allen screw for asa pin valve. Very used shape but works great! Could use a re anno. I have thrown these on nelson 007s, bushmasters, lapcos, ect just as they are and they work great. This item as the tiny asa for the allen screw which you will need to adjust to your liking. If you are throwing a 12 gram changer on this asa you don't need the tiny allen screw. Nelson with carter frame not included!
