22 ARC AR15 “coyote/truck” recommendations for a 16-18in

I’m looking to either have built or purchase a top-notch AR 15 in 22 arc with either a 16 or 18 inch proof, carbon fiber barrel. I will be adding a suppressor and will be using this mainly as a coyote rifle. I am out in Colorado and the longest I’ll be shooting is probably under 500 yards. The Alex pro elite LTR is the only AR that I have found that fits the bill. I would appreciate any recommendations on either complete uppers or full out builds. Thanks.

Not sure if you’re married to the proof barrel but you could have white oak or craddock build you a complete upper with in house, bartlein, geissele, etc barrels.

Since you plan on using a can will you go with an adjustable gas block/gas key/carrier?

Re carbon fiber barrels patriot valley arms also has carbon fiber barrel blanks they could profile into an AR barrel:
