Good but not great

I ordered 2 - I have a lot of good things to say about these receivers, with basically one glaring negative. Pros: Great price, easy install of all components (Aero Precision and Geissele trigger), I like the convenient features such as the built in trigger guard, threaded bolt catch pin, and tensioning screw. Cons: Magazine well tolerance is so tight that Magpul and Okay Industry mag's require a lot of force to insert and also require force to pull them out of the receiver. Even when fully loaded the magazines aren't even close to dropping out of the mag well without pulling them out. (D&H mag's seem to function properly). I would be less concerned if these receivers had issues with off brand magazines, however not being able to readily accept magazines from brands that essentially set the standard for all other polymer and USGI aluminum mags can't be overlooked. An AR that doesn't accept Magpul/Okay magazines is like a car that doesn't accept Michellin/Goodyear tires. Other than that these are decent receivers but will never be considered for serious use.

Doesnt play well with poly mags

Every thing went together fine and the finish was good Im not sure about the bolt catch pin because its wiggly. The main concern I have is it doesnt work well with my pmags which I have a lot of. My surefeed mags drop free. This should come with ten metal magazines

Does the job.

Hole for spring and deten that holds front pivot pin was not drilled to proper depth. Modified spring to make it work. Will get the job done.

Dont get this if for serious usages.

The lower is very nice, feels sturdy. However, I have one issue with it, the magazine release and bolt catch doesnt play nicely if you gently push the magazine in. The bolt catch will sit on certain magazine lips. This will not let it freely drop. There is some room to the bolt catch that might be causing this issue, the bolt catch wouldnt be straight but leaning left or right.
