Looks like a good base for my 6" build although I'll have to drill out the gas port.

Out of curiosity what size are you going to make your gas port for your 6" build.

.108 seems to be common for the real short 300blk barrels. I plan to run an adjustable gas block so if its a little too big it'll be alright.

Thank you for the info on the gas port size. I am not sure how well cutting down the barrel will work. I have been told that cutting down a barrel that had been processed with the black nitride finish (Melonite) can cause chipping. If you do end up doing it please post pics and let us know how it worked for you.

These were pre sold to our dealers at a super low cost to help get our product and name out. The barrels are headed to the finishing company now and should be back to us in a week hopefully.
If you have any questions please feel free to ask.
I just bought one for my first 300BLK build! Thanks! I'll write it up as soon as I get it running!

I bought one too. These are exactly what I was looking for to use on my pistol build and at a price too good to pass up. One blackout is just not enough. I must build more!

For those of you that ordered barrels. We were told today that they are done with the black nitride finish. Tme should have them back early next week and they should go out to our dealers. We welcome all of your reviews on our product.

If there are any dealers out there that wish to carry out product please send us an email at [email protected].

Will the muzzle threads be cut concentric to the bore for mounting a suppressor and reducing the chance for baffle strikes?

Yes, that is the design.

FYI - MAS defense has been randomly having sales on their 8" 1:8 300BLK chrome moly barrels for $109. Seem to have a good following and I haven't seen any negative results about their barrels posted on this board. I have been checking every day and have seen the $159 price cut to $109 twice in two weeks. Have to just drop out there and see.
