A lot of the major manufactures are jumping on the AR style 22 platform. Umarex distributes some real fun ones, I have the Walther/Colt M4 version, I like it and would be absolute perfect once I get a trigger job done. It is very very accurate and great for plinking and small game. The Umerax MP5 22LR looks BA. H&K 22 Rimfire - Home
They are nice clones, but to me, tactical 22LR is kind of an oxymoron, unless Colorado gets invaded by bunnies. Then its total carnage...oh the horror....the horror.....
I just bought a S&W M&P 15-22 at a local gun show for a good price. Son and I took it out today and put a couple hundred rounds through it. Great gun and we had a blast. I have no experience with regular AR style weapons but this one was light, shot great and I loved the adjustable stock and two size rear sight.
There is a very good article in the December issue of American Hunter magazine. Maybe you could get it online. It listed 8 mfrs. Of popular tacical .22's. My choice would be the Smith & Wesson M&P 15-22 because it's controls are just like the AR-15. A lot of the function buttons on some of the other mfrs. Are cosmetic.
My friend has a smith and wesson and its awesome great shooter seen it jam once but it was with remington ammo and we have had a few thousand rounds through. I'm interested in the mossberg because of price and I have a 702 and love it.
Personally, not a fan of the mossberg tac .22 when compared to the S&W M&P 15-22. Its the closest to the AR and its got a good warranty, it is pretty danm accurate with a pretty decently thick barrel for a stock .22, comes with 25 rounds mags, doesnt jam much..let see what else.... anyways, just my opinion. The S&W are a little pricey though.
Anything less than a Calico is a waste of time as a "Tactical .22lr", IMHO
Simply due to the fact of 100-rounds per magazine capacity.
If you HAVE to use a .22lr for home defense, at least you'll be able to throw a LOT of 'em
And for 2010, Calico came out with a Tacticool Carbine version with a 4-way pic rail...
With 100-rounds per mag, you can throw a lot of little bullets really fast with the "Bumpfire" technique.
The first 30 or so rounds will take out the first guy in the hallway, leaving about 70-odd for the next two guys...
But chances are, after the first Bumpfire is heard, they'll be running like heck!!
