The new CQCs are no longer coming with the BRH installed. In it’s place is a sleek new BRH Plug. We have found the BRH confuses customers as to how the M17 CQC works. Many think it is a charging handle. Many un-latch it by mistake, fire the gun, and damage their Bolt Guide Pin. The only function of the BRH is to clear a jam and we have found unscrewing the barrel works better than the BRH when clearing a jam.
If you have bent your Bolt Guide Pin in the past, or if you are looking for a cleaner look for your M17 CQC, we suggest removing your BRH and installing the new BRH plug.
