[QUOTE="vedauvoo, post: 2552959, member: 47024"] I recently built a very accurate 204 Ruger AR using forged aluminum upper and lower receivers (Aero M4E1-very affordable), a 24" Proof Research CF barrel, and a Trigger Tech Diamond 2 stage trigger. I picked an F1 Firearms DuraBolt TiCN bolt carrier group mainly for ease in cleaning. Since I shoot suppressed, I installed an adjustable gas block to prevent overgassing. I was a bit neurotic on securing the barrel to the receiver. I used a lapping tool to square the face of the receiver where the barrel extension butts up against the receiver face. Then I used Loctite 620 (green stuff) retaining compound between the barrel extension and the receiver surface. There are good YouTube videos on how to do this. I am just starting to reload for this rifle. But with Hornady 32 gr Superformance factory ammo, I am getting 4060 ft/sec and promising less-than-MOA groups. I think the gun is more accurate than the ammo (or me), so I can start cooking up some tailor-made ammo and work on my shooting technique. I wanted an accurate AR in this caliber for quick follow-up shots on coyotes. I think I've got a winner with this setup. And I love shooting this caliber! What a joy to shoot! I used a lapping tool to square the face of the upper receiver is a good accuracy enhancement ([URL]https://rifleshooter.com/2012/11/lapping-an-ar15-upper-receiver/[/URL]). Also, using Loctite 620 at the barrel-receiver interface is a good idea. [/QUOTE]
