From the manufacturer

The PW MK1 MOD 2-M line, revamped for 2018, features the PWS long stroke piston system. While the internals remain the same as other PWS lines, the MK1 MOD 2-M offers a variety of features exclusive to this line. Starting with patent pending PicLok technology on the free float handguard, users are able to mount either Picatinny or MLOK accessories on the front of their firearm. Moving to the fully forged upper, the craftsmanship of this upper can be easily recognized.
