I'm super excited to see the results on my old carbine.

I shot the 4.5" barrel at 50 yards on steel and couldn't miss.. it was nice not owning a shotgun anymore!

Zack, your 10/22 was Priority Mailed back today so expect Monday...
There is not much done new since its a barrel I designed for Midway and others, (like me CPC) back in 1992...
Receivers been here before and front barrel hole was straighten and .920" dia c'bore re-cut before your testing began...
Only thing new is the bolt... Bolt is new but badly scratched, bolt rework is done - but normally bolt rework is good for appox 15% accuracy increase... A stiff breeze will effect accuracy more than that... Action is slicked up a bit...
So I do not know what the results can or will be?

The final video is posted on You Tube...
Please go to You Tube, put in ct-precision.com in search...
There are 4 short videos, 2 on a chassis'ed 10/22, 2 are on a normal CPC 10/22 rework with a Midway bull...


(Interesting error in last video... My error for not asking... Other than - people getting their muzzles threaded for Sparrow silencers with a thread length .476" long they seldom tell me thread length... Rifle silencers are .439" long and pistol are .400" long... Its nice if they would include their thread length so I get it right)... (I guessed wrong)..

Yep, I didn't know it was an option for the thread lengths. I have a Gemtech Alpine and just kinda assumed most were the same, no big deal. I'm gonna chuck it up on the lathe here at work and shorten it.

I'm going to be writing it up for RangeHot.com soon to go with the videos.

So far the experience has brought the gun out of the safe and out to the range, which is awesome.

Yes...Threaded end has a backbored crown - so cutting .040" off will not effect the working crown which is appox .600" inwards... Looking forward to RangeHot.com report...
