Looking for the perfect foundation to build your own custom-AR for hunting? The new Aero Precision M4E1 AR receiver set ($242.98 in FDE, or $199.99 in black)—including both a threaded upper and stripped lower receiver—is an outstanding place to start. The upper includes a Picatinny flat-top rail, forward assist, while the lower includes an integral, enhanced trigger guard that dips down in the center—perfect for accommodating cold-weather hunting gloves. No controls, take-down pins or bolt carrier assembly are included. The FDE version is Magpul Cerakoted, while the black version is hard-coat anodized. Other features include a threaded bolt catch roll pin that allows for simple installation of the bolt catch and virtually eliminates the chance of finish damage during installation (pin included), upper tension screw that allows users to fine tune the fit of the upper and lower receivers with a nylon-tipped, tensioning set-screw in the grip tang of the lower receiver providing a tight fit, threaded takedown pin detent recesses, increased magwell flare for quick and efficient magazine changes, M4 feed ramps, .250 takedown pin holes and laser engraved T-marks.
