    I think ammo availability is only going to get better due to the hunting implications of the round in the Midwest states. Currently Iím getting he hornady Black for about 1$ round.

    I just bought this upper as well, for shotgun only hunting areas.

    I didnít want a bushy upper and this came with a decent looking MLOK rail and was about 1/2 the price of everything else, all also unproven, so figured what the heck.

    I wanted to get a 458 but that doesnít work in shotgun zones.

    I had a pre-built lower with an SSA-E trigger group and VLTOR A5 on the rear.

    Donít have a scope or sights for it yet but will post my experience once I get an optic installed.

    Word to the wise, check the gas port size. Mine came undersized and Iím turn was severely undergased.

    Yeah I need to get proper magazines before I draw any gas port conclusions.

    I have a 5 round bushmaster that works ok but a 20 rd unmodified lancer mag I have found to work the best.

    That Seekins rail is nice. The best part on the upper since it's not made by Radical lol
    How many rounds can you fit in the 20rnd mag?

    If you do a search on reviews of Radical Firearms, you'll see a lot of strange failures.

    7.62x39 barrels coming un-torqued under fire happened on several of them, for example.

    Well itís a hunting rifle so that isnít much of a concern. Almost by default it canít be worse than a shrubmaster.
