I need something like this for my hunting rifle.
No 7.62x39 bcgs on RTB?! Damn cant find one anywhere... Anyone know where to find one?
These are my preferred. Bought three about a year ago... since then their cost has shot up almost as fast as bitcoin has...
Running this is a 300 Blackout carbine. Works very well and very good quality. I’m a fan.
I have 2 of these... great BCGs .... when I do a build this is the BCG I prefer.... just out of stock a lot... always seems when I have extra cash they are out of stock
Really are a moron, aren't you son???
...and this coming from a Commie-Hillary d1ck sucker. Better to 'have' a candy truck than to be a 'candy', boy. Try using google once in a while, son.
What I'm seeing is basically $100... is there a code or I'm I just late to the party.....sure would like to pick up a few for that $59 price.......
