Like many makers of popular AR-15 rifles, South Carolina-based American Tactical tends to use polymer construction to produce lightweight and cost-effective designs. For those with reservations toward plastic, here is ATI’s Milsport RIA P3P, an AR-style rifle with a traditional metal receiver that remains affordable.
 

Milsport Design

This all-metal 5.56-chambered AR wears a 16-inch barrel with an HBAR profile and a 1:8 twist. It is a standard direct gas impingement design with a carbine-length gas system. The barrel and gas system are covered by a 10-inch free-floated M-LOK handguard, perfect for mounting accessories. 
 

Standard features include an A2 pistol grip and A2 birdcage flash hider. The buffer tube is mounted with an adjustable stock that includes a QD sling mount. Controls are traditional for an AR, not ambidextrous, with a standard charging handle and left-mounted locking latch. 

The rifle includes a Schmeisser 60-round magazine with a round count window. This magazine almost doubles the capacity of the traditional STANAG magazine but fits in a standard AR magazine well.
 

Summary

The ATI Milsport RIA P3P is a solid American-made AR that is extremely affordable. The customizable nature of the AR platform makes it easy to accessorize for your needs. Whether it is hunting, home defense, or just a fun range companion, this ATI is a great inexpensive AR-15.
