They're terrible... I went from 0 to 4 in less than a year. Ok, so 2 are only receivers... and in the "planning" stages... but I admit, shopping for them is just so much FUN!
BUT... if you have one, and complain about the "SPROING" of the recoil and buffer, there's a cure!!! In fact, the cure is so complete, both my complete rifles have been so equipped... and neither of the receivers will be completed without the same feature!
But, why do they do everything in "kits". One ends up with numerous extraneous parts laying about! Why don't the "kits" include just the basic parts, like pins and springs, and let you choose the parts you're likely to want of a better quality, without having parts of the "kits" that just become so much "trash" when you upgrade things like grips and triggers, mag releases, safety selectors and bolt releases! Bloody daft!
