When I got it back together I noticed that my scope seemed to be sitting off to one side. Some measurements confirmed, the scope rail holes were not drilled in the center of the receiver. The receiver top being rounded, and certainly not on the same radius as the barrel, means that in this scenario the farther out you dial and shoot the farther off windage will be.
This was not a tiny amount, it was off a good bit. While I know things mass produced are likely to have flaws, this was not a joyous moment.
The second issue was the barrel bore was not true but canted the barrel to the side. This as well simply pushed me toward replacing the receiver with something more precise.
I decided to order a Kidd receiver along with their threaded anti-walk pins and 20moa proprietary rail.
Then we found out that my mother has cancer. Full. Stop.
Recently I was able to get the project completed. In the future, receiver integrity will be verified before any other part of a project is begun. The core has to be right, or you will chase accuracy like a ghost.
The receiver from Kidd Innovative Designs is a thing of beauty. It is machined inside and out like a fine tool. The rail fits into a slot on the top of the receiver and all the screws do is clamp it together. In the factory design, the tiny screws hold all the weight of the optic from moving around a smooth rounded surface.
The Kidd bolt which is also beautiful had slid pretty smoothly in the factory receiver but glides like on bearings in this one. The barrel fits so tightly into its bore that it required a large plastic mallet and serious whacking to get it seated. Then aligning barrel to receiver also required some force. This tight fit ensures no barrel droop or problems with the barrel moving. Of course the bore is perfectly true and the barrel is now centered in the stock where before is was off to one side.
Speaking of the barrel, the rifle came with a 20" Kidd non-threaded barrel when I bought it. I had ordered a 16.5" Kidd threaded barrel for it and used it for the final assembly. It is incredibly machined and finished.
This is in a coated hardwood laminate stock by Boyds and is topped with a Primary Arms 4-16x first focal plane mil/mil optic with over 30 mils of elevation travel. With the 20moa rail this combo can get a standard velocity .22lr beyond 300 yards if wind allows. At 300 yards a standard velocity match solid is dropping 140+ inches so lots of dope is required and scopes without tons of travel need not apply.
I have not shot this thing yet. Hopefully I will get is zeroed and humming along this week as I have a get together next weekend where we will be taking .22s out to 300 yards.
I have said before, do not discount a precision .22lr for what is coming. Easy to supress and quiet when you do, accurate, easy to feed and penetrates like few understand with match quality solids.
Quietly impacting an 8" object out of nowhere tends to empower some, dishearten others.
Edited to add:
I have bolt .22s and I love bolt guns in general. Bolt guns will be slightly quieter suppressed and this cannot be discounted if absolute stealth is needed. As time has moved on, we have seen the AR platform not just meet, but beat bolt guns in competition. In comps where speed of follow up shots and engaging multiple targets are required.... semi-auto rules. There is a reason battles are not fought with bolt guns any more. Fast follow ups mean more dead enemies
Not having to shift grip or risk losing sight picture to move a bolt is a force multiplier. Hitting many targets in not much more than a second is reality with a good semi-auto .22.
In .22lr, the 10-22 pattern rules semi-auto accuracy. Can a CZ or Anschutz shoot very slightly better groups than a built 10-22 style rifle? Maybe, maybe not depending on specifics.
Can a built 10-22 style rifle engage multiple targets with incredible speed and pinpoint precision that makes the best bolt rifle seem ancient? Bet on it.
