Most Helpful Positive Review Well-made and affordable, straightforward A2 comp
No need to wax poetic about this - it's a straightforward A2 comp that will work with 9mm and 1/2-36 threads.

I mean how do you expect to get reviews for like small parts if you require 200 characters. If I got a Disconnector spring, like how would I even describe that for more than 200 characters.

Good affordable A2-style comp
