Q:
How long is the wait time for the 300 blackout 10" with 12" m-loc rail? Thank you for your time.
Asked by:

- 3/27/2021
A:
Unfortunately we won't have barrels until end of summer, so sometime after summer.
Answer provided by:
Black Rifle Arms Sales Team (4/20/2021)
Q:
Do you have a best guess when these will be back in stock? I'm not in a hurry. But do want before Spring. Any chance you know anybody that is incorporating your piston upper with an integrated suppressor?
Asked by:
Dave
- 1/4/2021
A:
We have no ETA when they will be back in stock. We can't procure barrel blanks to run more barrels.
