Planning my AR build but I'm continually frustrated by the lack of BCGs available for sale. I'm just looking for a standard MILSPEC phosphate BCG in the $130-$180 price range. Nobody's got them in stock. I must be on 20 different email notification lists, but still nothing. I've found some high-end NIB and Fail Zero EXO-coated BCGs in stock, but not ready to drop $250+ on these -- as I've read some problems with the gas tube not seating properly. Thoughts? Should I just keep waiting?
