Best 22lr ar?

I would stay away from the conversions that replace the BCG in your rifle. The one I had was not reliable at all and you've also got the wrong twist in your 223/5.56 barrel.
a dedicated upper is the way to go but I don't have enough experience with those to tell you which one is best.

I'm curious to know how these get around the magazine capacity limit for a restricted semi auto rimfire when the S&W M&P 15-22 can not?
Is it actually legal or is everyone just playing dumb? Being a restricted rifle I thought the law was different than it would be in a ruger 10-22 or other non restricted semi auto rimfire.
Hopefully I'm wrong because I've been very tempted lately to buy a dedicated upper and running the 28 round mags would be fun.
 
Magazines designed for semi auto rimfire rifles have no magazine restrictions. 15-22 shares a magazine with a pistol, therefore it has a 10 round cap.

That's pretty stupid. Yet another example of how well thought through our Canadian firearms laws are written.
I have very little faith that the NFA will be able to win the battle to make the AR non restricted but I sure hope they can get rid of these stupid magazine capacity limits.
 
Yup that is one that I looked at originally, I like that it's nr, but it felt really heavy when I handled it and its appeal was lost for me.

Unless you are very old or have a dissability of some kind, you should be able to get stronger and will not notice the weight.
I handled one a month ago and it felt well made vs heavy.
 
Are there after market mags for the sw mp15 so you can shoot more than 10 rounds?

You can buy a Black Dog 50 round drum mag and then install an 15-22 adapter tower (both available from Quester). It is also possible to modify regular BD mags to fit the S&W but I am not sure on the legality of that option ???

The gun the magazine is ultimately used in makes no difference. The type of gun it was originally designed/marketed for is all that matters.

The problem is the people who write the laws, IMO.
 
So many choices and decisions, if the sw mp15-22 didn't have the mag issue that would be a no brainer. Would prefer 30 round magazines. A dedicated cmmg lower/upper is $1k

From what I've read the S&W is the best one out there but I have no experience with it. The 10 round mags would make it more realistic as a training tool and would give you more practice doing mag changes.
Sucks to be limited to 10 but if the rifle is being bought to mimic using your AR-15 using cheaper ammo it would be a good choice. I've been very tempted to pick one up to see what they are like but haven't found the smokin deal I'm waiting for.
 
I have owned 2 different S&W 15-22 rifles. It is a great design and the most reliable of all the AR 22's in my experience, also the S&W 25rd mags are excellent . However, I decided to replace mine with a dedicated 22 AR for 3 reasons:

1) the STUPID 10 round mag limit (I did have a 50 round drum, but they are bulky and bit fragile)
2) the very light weight plastic feel of the rifle - it looks like an AR and functions like an AR but it doesn't really feel like an AR
3) the lack of barrel options - I really wanted a shorter barrel

My second 15-22 (moe version):

RRA / CMMG AR-22 & LMT 5.56 upper:

My CMMG's firing pin spring has exploded. It fell apart when I stripped the bolt after a range trip last weekend. I need to order a replacement from Brownells. It ran for about 2k rounds or so before it broke. Still works though.

I'm thinking of now either a:

From cheapest option to most expensive:
S&W mp15-22lr (cons - limited to 10 round mags)
CMMG - .22LR MK4 LE (cons - don't know how reliable the build quality is)
Colt6920 with a cmmg conversion kit (Con - most expensive and probably won't shoot a lot of 5.56 anyways)

A 22LR AR will be just as heavy.
 
If you don't want to shoot 5.56mm and only want to shoot .22LR your best bet is to buy a dedicated .22LR upper and build up your own stripped lower. The latter can be had for as little as $50, but average prices range between $100-$200. If you aren't handy at all you can buy a complete used lower for decent prices in the EE, or buy an entry level rifle and sell off the 5.56mm upper.

A dedicated rimfire bbl will always be more accurate firing .22LR as the standard 1:7, 1:8, 1:9 or even 1:12 twist rates are not well suited to the .22LR. The latter requires a much slower twist than its centrefire cousin.

A lot of .22LR ARs use a ton of plastic in their construction. If you prefer aluminum and steel, mating a dedicated rimfire upper with a centrefire lower will probably yield the most satisfactory results.
