Yankee Hill Machine is following up the successful release of its S.L.K. and KR7 KeyMod handguards with a new line of M-LOK rails: The MR7 and S.L.M.

YHM M-LOKs are perfect for tactical, sporting or competition shooters alike. A total of three different lengths are available: Carbine, Mid-Length or Rifle Length.

For more mounting surfaces, select from the MR7s, which can accept accessories at every 45 degrees. For a slightly lighter option, opt for the S.L.M.s with mounting platforms at 3, 6 and 9 O’Clock positions.

Both models feature a “T” marked extended top Picatinny rail, designed for a seamless transition from the Mil-Spec upper receiver.

The S.L.M.s and MR7s ship with all parts necessary for installation including a barrel nut, jamb nut, anti-rotation screws and installation instructions. Like all Yankee Hill Machine products, the new M-LOK handguards are covered by a lifetime warranty.

MSRPs on the two models are as follows:

  • S.L.M. CARBINE M-LOK: $190
  • S.L.M. MID-LENGTH M-LOK: $202
  • S.L.M. RIFLE M-LOK: $230
  • CARBINE M-LOK MR7: $127
  • MID-LENGTH M-LOK MR7: $139
  • RIFLE M-LOK MR7: $160
