From the manufacturer
The WORKHORSEA(R) M-LOKA(R) compatible rail system was designed to be a lightweight and slimline option to be used on MIL-SPEC carbines available on the market today. With M-LOKA(R) mounting options at the 3.6, and 9 o'clock positions and skeletonized areas where M-LOKA(R) is not used, this handguard not only offers function but shaves weight where it is not needed. Battle Arms still maintain 1913 MIL-SPEC Picatinny rail at the 12 o'clock position that we ""notch cut"" to match our upper receiver and reduce weight again. Offered in multiple lengths to accommodate different barrel lengths and different needs, the WORKHORSEA(R) offers everything you need and Mfg: Battle Arms Development Inc.
