Uppers n lowers fit perfectly w no jiggle at all.Very tight together which will be conducive to accuracy!

first choice


Forged S.T. receivers are tough, I have used them on a bunch of customers rifle builds. Always right, not fit issues, no blemishes and they take abuse.

Nicely finished, obvious quality


Very happy with this set. The FDE finish is flawless and the components themselves are first-rate.

Everything is great. The fit not so much. It is in between intolerable, and annoying.

Well made and looks better made than my Colt. FDE color is not the Magpul FDE but it is sharp none the less and is well applied throughout the set. Very sharp!
