    A chrome moly 1/9 twist that 99% sure hasn't been HP/MPI tested and inspected. Pretty much in the same category as BM, CMMG, Delton, etc..

    Good luck with it.

They have been very responsive to my multiple inquiries which is more than I can say about some others.

    Well, now everyone has me second guessing myself. I've already ordered the upper, so when it arrives I'll let the Armorer inspect it and go from there. Hopefully, it will zero fine and I'll have no issues. Worst case, I can probably sell it for what I paid for it and get a BCM.

    I am sure it will zero fine. But the last place you want to cut corners is on an SBR. If you have a Ned Christiansen chamber gage I would check it and see if it passes the test.

    Also another thing you need to consider is what size gas port they are using. I would contact them and ask. I'll be somewhat surprised if they can answer it.

    Nothing. It's just good to know if this thing is going to be overgassed from the get go because you will more than likely need to figure out which buffer to use.

    While you're at it, you could ask them if their barrels are true 5.56 or not. This way you will know if you need to worry about stuck casings.

    I asked your questions and it took a day for this reply:

    "Sorry I was out of the office on business. The port is roughly 78 and the barrel is in fact a 5.56 not 223."

    Well that's good news. Just remember with the 1/9 you will have to try out the loads over 69gr. to see if they will work in your set up.

    We're only supposed to use issued practice and duty ammo in departmental weapons; both of which are 55gr so I should be ok. Thanks.

    Yea I am about to do my first SBR build and I am hand picking parts from Noveske and Larue tactical. You definitely want the finest parts in your duty weapon. IT took me about a week to make my parts list. The total on the upper came out to $1,240.00.
