To finish off the lower receiver we slid on an FDE-colored Magpul SL-S 6-position carbine stock, which has an enhanced cheek weld and built-in waterproof battery storage. Note the FDE-colored Velocity Triggers QD End Plate (which you can read about elsewhere in this issue) which creates yet another attachment point for a QD sling swivel.
Our chosen optics setup includes a Bushnell Elite Tactical LRTS 3-12x44mm riflescope equipped with the first-focal-plane G3 Mil reticle (an ideal all-around optic for our needs and the gun’s chambering), mounted in a lightweight, FDE-colored 30mm Aero Precision Ultralight SPR one-piece mount. Magpul MBUS Pro Offset/flip-up sights were installed as back-ups.
Tah-Dah! Our finished product, wearing a Magpul M-LOK Bipod in FDE, Magpul MS1 Sling in coyote tan and the 5.56mm muzzle brake allowing attachment of the Elevated Silence Evolution suppressor that you can read about elsewhere in this issue. There’s a certain level of satisfaction in building your own rifle that cannot be replicated by purchasing an off-the-shelf rifle.
From the 100-yard bench, our newly-built Aero rifle turned in some seriously stellar performance using Federal’s 69-gr. Gold Medal Match load. This five-shot group measured just under half-MOA at 0.48-inches.
As of wrapping this article up, our Aero MK12 SP R-ish clone has around 450-rounds through its launch tube with nothing but reliable function. The rifle’s ejection pattern is between 3- and 3:30 o’clock when suppressed (depending on ammo), and since this rifle will likely stay suppressed 100-percent of the time, this is as close to ideal as it gets.
