The ATX "Billet 40" AR-15 Receiver Set is a very high quality and relatively lightweight receiver set. Unlike many other billet sets the Billet 40 includes a forward assist and is made from 7075 aluminium. If there is movement between the receivers you can use the tension screw that is included in the design of this upper/lower setup. The lower of the Billet 40 includes an integrated trigger guard so you won't have to buy an aftermarket part and install it. You can expect this set to withstand almost anything you're going to put it through since it is made to be very rugged and is also hard coat type III anodized.
