Q:
Can I get this 8" 300 BLK receiver with a BCG that is compatible with a law tactical folder?
Asked by:
Jae Jung
- 12/18/2020
A:
We don't have any plans to make modifications to our Bolt Carrier to allow for compatibility with Folding Stocks. Our polymer insert is in place to prevent carrier tilt.

Q:
Any eta on when this item might be in stock again? I was told you are waiting on barrels. Is that correct? If so, is there anyway to purchase this item that does not include a barrel, and would have to assemble upon purchasing my own barrel?
Asked by:
Zac
- 4/1/2020
A:
It's going to be a couple of months. The barrel blanks we use are not available due to the high demand of firearm parts. We have the order in for the barrel blanks but it's going to take a little while to get then manufacture them. If you have a barrel you like that is available and you want to drop ship it to us for a build off of it please let us know. We can look at the barrel to make sure it meets our specs .750" gas block journal with the gas block journal being 1.98" long.

Q:
Was curious what the estimated timeframe for availability?
Asked by:
Zac Bletz
- 3/10/2020
A:
Our current timeframe is 5 to 8 weeks. We are going to machine more barrels as this upper has become one of our top sellers. Sorry for the inconvenience, many are signing up for the Waiting List which will notify them through email as soon as they go back in stock.
