    Perfect fit

    Previously purchased a KAK AR10 upper and paired it with a PSA lower. I had to muscle the KAK upper down onto the PSA lower though it ran just fine. When the KAK K10 lower was re-stocked in inventory, I purchased it. Shipping was fast. Grunted the PSA lower off and dropped the KAK upper onto this lower. Fit perfect. Shoots like it was meant to. With/without the suppressor using the KAK down vent BCG.

    Well-made high-quality lower receiver. One of the best complete lower receivers I’ve ever purchased. Fast shipping and Nice people to deal with if you have a problem. I will do business with KAK again.
