  1. I don't like those extended charging handles they dig into body if u sling the rifle. Why 10.5 inch barrel for a 300 blackout 8 inch is just about fine for a pistol. Get 10.5 for 5.56.

  2. I'm actually in the process of ordering all the parts to build my 10,5" pistol on a spikes matched receiver set. I've got the kak buffer tube Ann blade brace along with a bagara nitride barrel on the way. I'll be going down to AXC tactical this week to pick up a 10' slim line key mod friend and the matching steel barrel but. I already have the nickel boron bolt carrier group and trigger hammer disconnector combo,which I've done a trigger job on and has a 3.5 lb pull. it will get sbred. my next step will be the suppressor paper work.
    yours turned out very nice. thanks for the heads up about using an h2 buffer and the idea of color coding for caliber.

  3. should have gotten a better barrel man. ballistic advantage is my go to. you could have gotten an moa guaranteed barrel for the same money as the radical firearms barrel. as far as quality and affordability combined….ballistic advantage is impossible to beat
