The AT3 10.5 inch 5.56 NATO JNL Ready Build Kit is built for customers who want a compact pistol upper and only need to supply a stripped AR-15 lower receiver. It combines a 10.5 inch 5.56 assembled forged upper with a 9 inch free float quad rail, A2 flash hider, black nitride BCG, and charging handle, plus the lower components needed for a brace-equipped AR pistol build.

Note: This kit includes an assembled pistol upper receiver and lower build components. Stripped lower receiver is not included, and lower parts are not assembled. This kit includes a pistol brace, not a rifle stock.
