Steve These 22 kits are great for plinking but there's a definate loss of accuracy. Still good fun for a quick change. They do however drop a lot of crap into the lower reciever. If you wanted the accuracy I'm sure Matt and the guys would recomend a dedicated 22 upper Cheers Taffy dont forget these are on-ticket items |
Not easily. You'd be better off getting/making a dedicated 22 upper using the ceiner bolt and mags. The main problem is the bullets are presented in a completely different position. But I hear CompassLake (I think) have parts available. |
I used to get great accuracy out of the Ceiner kit and a 1:9 barrel and CCI MiniMags at 25 yds. Still got some of the old 25yd high power targets we shot at the club of a winters night. Regularly shot over 90ex100 and on two occations shot a 99. X counts were extremely hard to judge and without a spotter calling every round you'd never find half the holes. |
On the subject of builds… Savage quoted me @£300 for a .22 barrel, seems a bit steep paying £300/foot!!! Can you do one? 12" nothing fancy, just a threaded end. Andy |

fitted for a M261 bolt (a la Bremmer)? If that's the case then it'll be more from me as I'm not set up to make them and the machining time will be high, there's a lot more work involved in a rimfire dedicated barrel than there is in the full-bore version. I believe Savage has them already made (from the Bremmer sell off I think). £300 seems a bit much for what he most likely got as bankrupt stock (or whatever) but if he made them then it's not too bad a price. The blanks are the same price whatever the calibre and then it's a case of adding the maching time etc. and he's got the CNC machines to do the work easily (and most likely the programs already written). |

Am I right in saying (reading the firearms act here) that I can legally own a semiautomatic rimfire AR carbine because it's not a fullbore firearm? Or is there some strange clause that recognises it as an AR and hence can not be semi (ie-must be straight pull)? I ask because the closest range to me apparently isn't really set up for full bore use and would me very nice indeed to practice on a semi .22 carbine. |

I am sure that is a ceiner kit. Accuracy improves with a slower twist. This is a kit, so fullbore functionality is restored with removal. A dedicated .22 upper is a different beast entirely. These are permanently .22lr unless they are rebarreled and parts are replaced. They can also be very accurate. Mine prefers RWS Target and functions 100% until I get some 700-1000 rounds through it. I am using a jewel trigger and it gets filled with junk. I have cleaned the A36 (12 bull international target, 50 foot, .5mm 10 ring) 4 times. It is generally good for high 90's if you are. They are useful tools for training. HTH.....SRM |
Basically as I said above. Great for high power training, or anything else where you'd normally use the full-bore version in competition ( I think I'm right in saying 'high power rifle' in the US is synominous with 'full-bore rifle' in the UK, as well as high power being a competition discipline). With the insert you get the benefit of exactly the same rifle, with trigger feel, weight, balance etc, just less expensive ammo, and the ability to play/practice indoors with reduced recoil. The dedicated 22 uppers are better for accuracy as they have a better chamber, less 'free-bore' (by about 1.5"!) and more appropriate twist (typically 1:14"). If you use the full-bore lower then you still have the same trigger feel etc, and the weight/balance can be made as near to your full-bore as you want. |
Yes, Savage has a big pile (@300 I think he said) of them along with the lowers he got from Parker Hale when they went tits up. Trouble is he has no M261 bolts, he bought the rights and all the remaining ones from SARCO but has gotten around to making them. £300 for a bankrupt stock .22 barrel is very steep when you consider you can get a complete DPMS based dedicated .22 upper from £400 from Oberland Arms! www.oberlandarms.com/pdf/waffen/langwaffen/oa_22_22lr.pdf |
Following on from earlier I've taken these pics to show the difference between the M261 and the Ceiner bolts. As you can see the bolts are different lengths so will be able to move different distances within the cinfines of the upper.  The Bolt carriers/guides. As these hold their respective chamber inserts differently the mating slots in the barrel would be different and need to precisely aligned so the bolt doesn't snag.  M261magazine and AR carrier-mag (on left) and the Ceiner mag on right. You can see from these two pics that the ceiner bolt has to move further back to be able to pass the round in the mag and pick it up. The M261 mag presents the round closer to the chamber and at a different angle. I haven't tried the M261 mag with the Ceiner bolt, but as these kits sometimes cause the round to go off before it has fully entered the chamber (I've got scars to prove it  ) trying this would be a recipe for disaster.

I see your M261 spring retaining clip has done a dissappearing act as well - or have you just removed it? |
It's gone  It left home the day I got it, and the E-Clips for the AR dust cover hinge don't fit. So I just get by. The only time the rifle gets opened up is when it's cleaning time, and then the bolt gets stripped before it goes into the ultrasonic bath anyway. If it needed removing and storing so the upper could be used as a 5.56 then it'd be a different matter. I'd either get another E-clip or drill the guide and fit a split pin (or  ).
