Smith & Wesson announced that it was now shipping a pair of its M&P rifles that have been updated with M-LOK gear. The two rifles that were updated are the M&P15T and the M&P15X. (Earlier in the year, the company began shipping the M&P15 Sport II with M-LOK.)

Both the -T and the -X share many common features and specifications. Some of those commonalities are:

• receivers: forged with hard coat anodizing; the lower has an integral trigger guard
• barrels: 16″ threaded barrels made of 4140 steel; 5R rifling with 1:8″ twist; Armornite finish
• muzzle device: the company’s own patented flash suppressor
• rear sight: Magpul MBUS
• magazine: 30 round Magpul PMAG
• stock: M4 style adjustable
• pistol grip: A2 style
• forward assist: yes

The major differentiator between the two relates to the gas block and the parts affected by this. The -X version of the gun uses an A2 style front sight base. Matched with this is an aluminum, carbine length hand guard. The hand guard is a Smith & Wesson product with M-LOK attachment points. The company includes a 2″ length of Picatinny rail to use with the M-LOK if you have an older light or other accessory you need to hook onto the gun. This gun has a suggested retail price of $1,239.

The -T version of the rifle uses a low profile gas block. This allows the company to use its 13″ long hand guard. This hand guard is also designed to the M-LOK specification for accessory attachments. Since there is no front sight tower, the company includes a Magpul MBUS front sight with the gun. The MSRP is $1,190.
