https://greyhive.com/videos/watch/b0a4add3-4995-4731-9ef3-dfdd60c1a3ce I am adding another caliber to the precision rifle series: .224 Valkyrie. Here are the parts. The receiver set is an Aero Precision M4E1. I like these for a few reasons. They are forged, with a billet look, at a forged price. The bolt-catch and forward-assist pins are threaded. With one arm, I do not need someone else to punch roll pins. The internals are from JP Enterprises. This is my third JP bolt carrier group, their ultralight aluminum carrier. A carrier this light needs an adjustable gas block. Tune the system so only enough gas comes back to eject and feed. If you overgas an aluminum carrier, wear climbs and service life drops. The trigger is a JP Fire Trigger kit with the roller shoe. Full install and adjustment are in the 6.5 Creedmoor Part 1 video. The pistol grip is a discontinued Strike Industries model. I bought extras while they were available. Dimples on both sides accept a finger bump so only the center of the trigger-finger pad meets the trigger. That matters when I shoot with one arm. Anything that reduces wasted motion leaves more attention for the hold and the aim. The stock is a Magpul PRS Gen 2 I bought from a friend. I still prefer it to the Gen 3 because the monopod interface is flat, not angled. Inside are a flat-wire buffer spring and a CTS Engineering active recoil buffer. Left-side controls are Forward Controls Design: an extended bolt catch and an ambidextrous magazine release. The catch stands far enough out that you can lock the bolt without hitting the ambi mag button. It is a strong pairing. Up front is a 17-inch Odin Works Ragna handguard. I like the cutouts and the weight. Seventeen inches lets me put the bipod at the muzzle end for more leverage and finer aiming inputs. The barrel is a 20-inch Tactical Kinetics .224 Valkyrie. On the muzzle is a SureFire three-prong flash hider that also serves as a suppressor QD mount. That choice is one of the accuracy details I have been posting about on Instagram and Facebook. The gas block is an SLR Rifleworks Sentry adjustable unit. I use these on almost every build. Being able to tune for the rifle and the load matters, and their machining is consistent. The optic is a Vortex Viper PST Gen II 5–25×. The bipod is an Atlas on an American Defense QD mount, itself on a Kinetic Development Group M-Lok QD section so the whole setup moves from rifle to rifle. That is the Valkyrie build.
