FAQ

What Does Different Receiver Forge Marks Mean?

ar15 receiver stamps

Forge marks on AR15 represent the company that makes them. The quality among receivers is pretty much the same with very small differences in tolerance.

What's The Most Important Spec For An AR15 Upper Receiver?

Billet VS forged are two different type of receiver.

Billet has better pattern cuts while the forged receiver supposed to be stronger. In our opinion, both works very well, and you won't go wrong with either one.

An AR15 upper receiver doesn't have to be more fancier than what it should be. Another thing to focus on is the M4 feedramp.

Referenced LaRue Tactical

The M4 feedramp is milled into the receiver that extends down the edge of the barrel extension. It should match with the barrel feedramp.

Any mil-spec receivers on the market today should all have this.

Forward Assist Vs No Forward Assist

Forward assist helps to seat the bolt carrier group if a round doesn't chamber completely on an AR15 rifle. It can come in handy in malfunctioning situations.

A receiver without the forward assist still functions, but make sure the buffer system is strong enough to chamber the round.
