Anyone ever use this: http://www.brownells.com/aspx/ns/st...p=5478&title=SEMI-AUTO+.22+LR+CONVERSION+KITS

Just wondering on reliability and accuracy in an AR with 1:9 twist

It's a Ceiner kit, btw. I have one, Brownell's price with a C&R discount is $114.

They are hit or miss, but with Brownells fear not because if it doesn't work they'll take it back no questions asked.

Most of the issues with Ceiner kits are magazine related....mainly feed lips need tweaking, from what I have gathered. I only have a 10 and a 30 rounder at the moment, but both work like a champ.

A 1:9 twist is fine, mine shoots 1" groups at 50 yards with CCI mini-mags.

I have had two Atchisson conversions and they were both problematic because the magazines were cheap POS.

I now have a military surplus M261 unit and have found it to be far superior to the commercial offerings.
I would suggest you find an M261 unit instead.
If you can locate one, I have the M261 manual in PDF format which I can email to you.

I'm headed out of town for a few days right now but if anyone needs one of these M261 manuals, email me and I'll send you a copy when I return.

I only found 1 M261 kit and it was 285+shipping+FFL transfer

Is this the going rate or typical gunbroker?

If the only drawback to the Atchisson kit is the mags, then can you upgrade to something else?

I've got one of the Ceiner kits for my AR and I guess I just got lucky - have about 500 rounds through it so far w/o cleaning (the kit, not the AR ) and it's worked like a champ since round 1. I also like the fact that it loves the Remington bulk pack ammo.

If you get the Ceiner kit, you may also want to get the Lakeside springs - folks that had trouble with the Ceiners said that most of the problems go away with the new spring. I put a Lakeside spring on my kit and it's been flawless.

There's also a guy that goes by the name of M60joe and he makes loaders for the mags...expensive but you can load the mags in seconds.

M261 kits can be had for less money. I got mine for under $100.

Try checking the AR15.com equipment exchange. That's where I found mine.

I have had good luck with the Ciener 22 conversion kit. It just replaces the bolt with a clever little 22 mechanism. Only annoying thing is that it does not hold open automatically when the magazine is empty.

They recommend only using high velocity copper plated 22LR, which I have been doing.

No complaints so far. Surprisingly accurate!

i've got around 3000 rnds through my ciener. it's ok. it hates remington ammo. works best on the federal packs of 550 from wallyworld. it runs just fine on the supersniper and other subsonics. super colibri works fine, but doesn't cycle the bolt.

one thing about it though, is that it gets the inside of your upper receiver MUCH dirtier than normal, believe it or not. and it's that gritty 22lr dirt, not your regular HP carbon cake. i think it has caused my BCG to wear a lot faster than normal.

I've found the .22 conversions rather picky with ammo, and never really had much success in the accuracy department. For an extra $100, I would suggest a dedicated upper like the one that CZ makes (if you can find it). Somewhere I read that the Ciener mags can be modified to work with this upper, but can't remember who said that. SC

I am generally amazed by the wide opinon range on the Ceiner.Mine was a little fussy at first but overall it has been very wonderfull for me.There is a troubleshooting list banging around on the internet,mostly dealing with the feedlips of the mags and how to adjust and measure them. I have bought two different 30's and two 10s and never had to do anything but clean them from time to time.
I shoot my Ceiner with several different uppers ,includeing two different 1/9 bushmasters with no problems.Very ammo dependant,Mini Mags very reliable only so so in accuracy as is most high velocity stuff.My Unit after it got broken in handles standard velocity target ammo well and it shots much better groups compared to the high velocity. Wolf MT is the stand out performer. I use no oil,only spray can silicone,unit runs cleaner much longer than with oil.

If you plan on a lot of shooting, you might consider just buying a dedicated .22LR upper instead of the conversion. A little more money up front, but worth it in the long run.

I have a Ceiner unit and as noted it doesn't like bullets with exposed lead. I have a 10 and 30 mag and both work pretty good on my SP1. Have not really shot for groups but fun for plinking.
