There was a misunderstanding about how long I needed the rifle to test several barrels, so I had to send it back early. That may have worked out. As I returned it, Aero Precision released the M4E1 upper and lower. I liked the minimal look. They also brought an AR-10-style feature onto the AR-15 lower: a threaded bolt-catch pin instead of a roll pin. That is easier to install, especially with one hand. Here is the finished 6.5 Grendel. On the right you see the Aero M4E1 set. Internals are again JP: Easy Trigger with the Armageddon Gear Revolution roller, and their VMOS carrier. The VMOS lets you change rear weights to tune cycling for small-frame calibers or a suppressor. Magpul PRS Gen 2 stocks are hard to find, so I used a Gen 3. On the left, as on the 6.5 Creedmoor, I used the Strike Industries grip with the finger-bump shelf so the last pad of the finger sits on the trigger. With the roller trigger I can think less about the finger and more about the rest of the shot. Magazine release and bolt catch are Forward Controls Design: ambidextrous mag catch and matching bolt catch. The catch is extended so you can lock the bolt without hitting the mag button. The charging handle is Strike’s latchless model with an ISO tab. I put a red tab only on the left so I can stay in the scope and still find the handle in peripheral vision to load or clear. The rest of the cycling system is a Strike flat-wire buffer spring and another CTS Engineering anti-tilt active recoil buffer. The nub is meant to keep the carrier centered and limit tilt. Some people say tilt is only a piston-gun problem. I think it happens on direct impingement too, just less. I covered this buffer in an earlier video. In part two you will see a fitment issue between the anti-tilt buffer and the JP VMOS carrier. The barrel is my third composite: an 18-inch BSF 6.5 Grendel. BSF uses carbon fiber differently from Christensen Arms and Proof Research, the other two wrapped barrels I own. A comparison video is coming. On this barrel: SLR Sentry adjustable gas block, SLR nitrided gas tube, 6.8 mm SureFire SFMB, and a 17-inch Strike rail. I used to run a Harris bipod on the Creedmoor. I have since switched to an Atlas on a Kinetic Development M-LOK QD mount so I can move it between the Grendel and the Creedmoor. On top is an American Defense 30 mm QD mount with an Athlon Ares FFP 4.5–27×. I want to see how it stacks up against the Vortex Razor on the Creedmoor. That is part one: the parts list.
