SPRINGFIELD, Mass. (January 19, 2009) - Smith & Wesson Corp., the legendary 157-year old firearms maker, announced that it would expand its Military & Police (M&P) Rifle Series with the introduction of a new tactical rifle chambered in .22 LR - the M&P15-22. The dedicated .22 LR platform offers the fit and feel of the company's popular M&P15 rifle, while being chambered in the more economical ammunition.

Engineered on a high strength polymer upper and lower receiver, the M&P15-22 benefits from reduced weight while retaining the looks and operating features of the standard M&P15 rifle. The new semi-automatic rifle features a 16-inch barrel with a twist of 1 in 15 inches. The M&P15-22 is standard with a six-position collapsible stock to accommodate a variety of shooters and shooting positions, an A3 style flat top upper receiver with a quad-rail handguard for easily mounting optional accessories and an A2 pistol grip for improved firearm control.

The new tactical rifle also features a fully functional charging handle, an AR-15 style magazine release, bolt catch and a two-position receiver mounted safety. The M&P15-22 is complete with a removable 25 round magazine along with a removable A2-style front post sight, an adjustable A2-style rear sight and a single stage trigger. An optional barrel shroud is also available.

"In designing the new M&P15-22, our engineers pulled out all of the stops to develop the ultimate .22LR platform," said Tom Kelly, Vice President of Marketing for Smith & Wesson. "The rifle's operating features, functionality and durability are exactly what you would expect from any of Smith & Wesson's tactical rifles. By remaining true to the standard AR-15 design while offering all of the preferred features found on the M&P Rifle Series, the M&P15-22 is well suited for a variety of recreational shooting applications while also being an extremely viable training firearm for law enforcement and military personnel. Shooters will find the M&P15-22 to be a great firearm for multiple uses with the reduced recoil and economical .22LR caliber ammunition."

The M&P15-22 has an unloaded weight of approximately 5 pounds. The rifle measures a compact 31 inches with the stock collapsed and 34 inches with the stock fully extended. The M&P15-22 is designed to accept all 1913 Mil. Std. rail adaptable accessories, Mil-Spec carbine stocks and most standard after-market AR-15 pistol grips.

The new GSG-5 .22 caliber semi-auto rifle from American Tactical Imports is an exact replica of H&K MP 5 sub-machinegun aside from the caliber.  Ergonomics  and handling are identical to that of  the MP 5 with an overall length of 33.5” and a weight of 6.6 pounds which makes it an ideal training tool for Law Enforcement, Military personnel or civilians. 22 long rifle offers an immense savings over 9mm/40/45 caliber ammunition allowing extensive range time with the GSG-5 at a minimal cost to the user.  

Barrel length on the GSG-5 rifle is 16.25 inches including the faux suppressor which surpasses federal requirements  making it legal to own by anyone.  The GSG-5 utilizes either a 22 or 10 rd detachable box magazine that releases with an H&K style paddle magazine release.  The charging handle on the GSG-5 is located on the left side of the receiver and is non-reciprocating just like the H&K MP5 series.

The GSG-5 comes standard with a conventional MP 5 style stock and forend but American Tactical Imports also offers several different style stocks and tactical forends including a side-folding stock like the H&K MP5k-PDW and a retractable stock as offered on the H&K MP5A3.  The GSG-5 comes with a standard H&K style forend but is upgradeable to a tactical railed forend that accepts tactical grips, lights and lasers. 

The GSG-5 utilizes the H&K style Drum sight that is windage and elevation adjustable.  Accessories available for the GSG-5 include a claw mount with picatiny rail allowing just about any optic from a tactical or hunting scope to a Close Quarters Battle optic like a red dot sight to be mounted on the receiver.   In addition to extra magazines ATI also offers a tactical magazine coupler for joining 2 magazines together making for a faster reload.   American Tactical Imports also offers an MP5SD style barrel/faux suppressor that looks exactly like the original.  Whether you are looking for a low cost tactical trainer or a fun plinker the GSG-5 rifle is a winning choice.

Can this be threaded to accept the standard M4/M16 flash hider?  Doesn’t look like it to me.   A very specific platform.

Colt and Umarex have teamed up to produce the Colt M4 .22 Tactical Rimfire. The is probably the only real “Colt M4″ you will ever be allowed to own!

I am not 100% sure they are in fact AR-15s. UMAREX USA uses well known brand-names such as Beretta, Ruger and Walther to sell their airguns. This could easily be a AR-15 patterned rifle much like the .22 GSG MP5 or GSG AK.

There will be four different models.

Colt M4 Carbine

* 16″ Barrel
* M4 collapsible style stock
* A4 flat top upper recoever
* detachable carry handle
* A2 flash hider
* A2 pistol grip
* 30 round magazine
* Weight: 5.95 lbs

Colt M4 OPS (includes the following extras):
* Rear BUIS (Backup iron sight)
* Free floated aluminum picatinny rail handguard

Colt M16
