Quoted: Is there something wrong with the upper now?

No, there is no problem associated with Kuehl. I am trying to get a precision rifle, and in the world of the 22lr, precision demands the use of subsonic ammo. Although the rifle still works fairly well with this ammo, about 10% of the rounds don't cycle it properly. Additionally, I've noticed that the bolt is shaving lead off the top round in the magazine, which is not going to help accuracy one bit!
While I'm sure I can start polishing, honing and tweaking the unit to work well, my other thought was to just convert the caliber to 17 Mach 2. This would have the following advantages:
- These rounds are highly accurate at a slightly higher cost than the high end 22lr ammo I'm shooting. I'm using Wolf Match Target at the moment.
- The bullets are copper jacket which will resist shaving
- The 17M2 has sufficient energy to cycle the action without all the work. In fact, I'll more than likely need to add a stiffer spring and some mass to the bolt.
- The resulting rifle will shoot very flat with a bullet that is extremely destructive on small game. In other words, this will become my preferred jackrabbit gun, with 30 round mags available.
- I'd be the first kid
on my block in my zip code to have one!
ARFan,
Thanks for the heads up on the rounds. I've been hanging out on
www.rimfirecentral.com and they have plenty of good info there. I might drop you a line to share ideas.
Anyone know if you can ream out a 5.56 barrel and put a .22LR barrel liner in it?

Yes. This will help the functioning of the Ciener unit as it improves the gas seal. I just don't know where to go. The next step up would be a dedicated barrel that dispenses with the Ciener chamber adapter.
