So far my interest in the AR platform has been for the purpose of coyote hunting. (Its about to change as I'm wanting an AR for plinking/carbine courses, but that's another story)
After being a bolt guy, I decided to take the plunge and get an AR. It worked well for me last year on quick follow up shots. The current one I have is an 18" in .223. I decided to let my son use this one for the upcoming fall/winter coyote season.
I wanted a different caliber, so I began doing some research and came across some guys that were using a 6mm DTI with great results. It is a 6.8 case necked down to 6mm and will be fire formed to push the neck to a 30 degree angle. So I will be pushing a .243 bullet faster than my .223. This should help with wind drift.
This upper was built by Mike Milli at Dedicated Technologies. This caliber is his design. He also incorporates an integral compensator to help with muzzle rise.
I call this Phase 1 as this is the new upper however, it is on my current lower. I am going to assemble a new lower (Phase 2) and then have it dipped in camo for Phase 3.
One thing I noticed, is when I purchased a PRI 6.8 magazine, that guys were getting away with longer COAL on these loads. I have some 2.290 COAL so this is a big change from what I was loading for .223
I know most AR's on this forum are of the tactical version, but thought you guys might want to see a different kind.
Anyway, here is the new upper
6mm DTI caliber
22" Shilen Select Match SS barrel, hand chambered and profiled
Fully fluted barrel
Custom integral compensator
Mike own free float tube with sling stud.
6.8 DTI on Left .223 on right
Can't wait to get it out and shoot it.
