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 rifle has different models that come chambered in 5.56mm NATO/.223 Remington, .22 Long Rifle, and 5.45×39mm. The barrels come with either a melonite lined or chrome-lined 4140 steel rifling, and 7075 T6 aluminum receiver with a hard-coat black anodized finish.

In 1963, Melvin M. Johnson developed a conversion of the M1 Carbine (by either relining or re-barreling the M1 Carbine ) to a .224 caliber bore, using ...
It also cited less sensitivity to extreme temperatures for the 5.7×28mm and cited a greater potential risk of barrel erosion with the 4.6×30mm. [7] In addition, the group pointed out that 5.7×28mm is close to the 5.56×45mm NATO by its design and manufacture process, allowing it to be manufactured on existing production lines. [ 7 ]
The Steyr SPP (Special Purpose Pistol) is a semi-automatic variant of the TMP. The TMP's barrel and barrel jacket lengths were increased slightly so there is a greater length of protruding jacket and barrel. The forward tactical pistol grip was also removed.
