The Modern Scout Rifle: Lower Completed


I mentioned that I had picked up an AR-10 Armaspec lower parts kit with an FDE selector lever and magazine release button. I've now installed that in the lower receiver. I have to say that I really like the shorter throw--I think it is a 45 degree--on the safety selector lever.

    The trigger is a BCM PNT Trigger Assembly. I wanted a trigger that used mil-spec type parts for ease of locating parts or repair should something go wrong. Bravo Company has polished the trigger, applied a nickel plating and Teflon coating which makes the trigger very smooth.

    The backplate, castle nut and buffer tube are standard AR parts--I used the Aero Precision brands, but there is nothing special about them.

    I can't find the packaging, but the buffer is a shorter AR-10 buffer (you can't use an AR-15 buffer because they are too long) and a flat coil spring intended for the AR-10/AR 308 rifles.

    The stock is a Mission First Tactical Battlelink Minimalist Milspec Stock in their scorched FDE (which matches the Magpul FDE).

    Finally, the pistol grip is a basic Magpul MOE-K grip in FDE.

    Total weight of everything you see in the photograph, including the stripped upper, is 2 lbs 6.6 ounces according to my scale.

    I still have some parts to collect for the upper.


  1. Aero has made some improvements on the receivers that make it much easier to assemble.

    1. This one is very similar to the Aero receiver in that it has a threaded pin rather than a roll pin to hold the bolt release in place.

  2. You never told me you were getting me this for Christmas! You're the best!

    1. You're right. I am the best and I didn't tell you ;-)
