The M&P15-22 was designed to be a less expensive alternative for training with an AR-15 style rifle, as the rifle itself is much less expensive than most AR-15s, and the .22 LR ammunition is often much less expensive than the .223 Remington/5.56×45mm NATO. The rifle features a safety and bolt lock that operate just like an AR-15's.
The Compliant model (designed for the California market) has a CAR-15 stock fixed in the open position (with an overall length of 33.75 inches) and comes with 10-round magazines. [ 14 ] The Smith & Wesson Performance Center target shooting version has an 18-inch bull barrel threaded to take any AR-15/M16-style compensator, a free-floated forend ...
The Smith & Wesson M&P22 is a semi-automatic pistol chambered in .22 Long Rifle. It is hammer-fired and blowback-operated, and differs from the centerfire M&P variants, which are striker-fired and recoil-operated.
A powder with a slower burning rate is used to make the most use of the length of a rifle barrel. Most .22 long rifle powders increase velocity up to about 19 in (480 mm) of the barrel. The powder used in the Stinger increases velocity up to the longest .22 barrel length tested by the NRA, 26 in (660 mm). [24]
A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.

The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
Individual soldiers were often forced to carry a breaching shotgun in addition to their standard-issue rifle, but the Masterkey removes this need. The system consists of a shortened Remington 870 12 gauge pump-action intended to be mounted under a firearm's barrel, similarly to the M203 grenade launcher. It has a 3-round internal tubular ...
