    Question: What is the difference between mid-length and rifle-length gas system? I have googled a bit, and got mixed results. Which would be preferable for an 18.6" barrel?
    Rifle length will give you the best reliability.

    Iíll also have a 300blk, 9mm, 762x39, and 223/556 Upper. Maybe 2 lowers. As funds become available of course.

    I wonít take up anymore room in this awesome thread.
    For the 7.62x39 would you only need a specific 7.62x39 bolt and barrel? Is there anything else that needs to be done to the feed ramps etc?

    So what's the deal with 6.5 Grendel bolts? In my internet wanderings It has been shown to be an incredible round. (In my opinion the ideal intermediate cartridge. Or at least thus far.) But the bolts look incredibly fragile. Has anyone made a proprietary bolt/barrel extension yet? I know NEA did something along those lines with their 7.62x39 guns.

    Gonna strip a lot of parts off one of my ARs for my 223 build and then gonna get a second upper for a 6.5 build.

    Subbed for ideas.

    JP Enterprises 6.5 grendel bolt. Don't buy anything else unless you like things blowing up beside your face.

    A lot of guys go with the JP bolt.

    For the 6.5 bolt can you use any 223 carrier?

    That’s ridiculous. I haven’t seen any problems with Toolcraft BCGs, their BCGs cost $50 USD less than a JP bolt.
