can any one tell me about this AR type of rifle good or bad that Mossberg making
It's called the Mossberg Tactical.
Some really like them. They have a good .22 action and barrel housed inside a plastic shell. 25 round mags.
Some say they give the impression of being a cheap, lightweight toy, like something you'd get at Walmart in the toy section with a red muzzle.
I read a bunch of reviews on them. I do like the looks of them, so I seriously considered one. Some say they've fired thousands of rounds with barely a hiccup. Others say they are a total Jammomatic, especially if you hold the mag when firing. I have read the same thing about virtually every Tacticool .22 out there. All of them are very ammo sensitive and you have to try different types before settling on what the rifle prefers.
There is a new Flat Top model coming out soon. I was told to expect them in February hopefully. If you want one of them might be worth waiting for that, most prefer that setup for optics.
Ultimately I decided against the Mossberg Tactical, opted to go for a Squires Bingham/Armscor M1600 when I belatedly found out they were still for sale brand new. (real wood stock, steel receiver)
BTW, the Armscor is about the same price as the Mossberg Tactical or even a bit cheaper depending on the dealer. If you can manage it I'd suggest holding both of them before deciding what to do. On one thread a poster mentioned changing his mind about buying a Mossberg after handling it.
* On the Armscor, to mount optics, slide the carry handle off the receiver grooves, slide on a B-Square Picatinny rail adapter, then install the optics of your choice. Same location as on a flat top.
