    Lingle poly lower

    Works great. Owned the competitors polymer product and sold for this. Very glad that I did. Fit and finish are superior and the bolt-catch was worth the swap alone. I use AK-V mags solely. Liked it enough to SBR my stribog.

    I got the binary trigger, magpul grip, Scorpion Mags by Magpul and PSA AKV. LRBHO worked perfectly with new bolt catch.
