The MK2 MOD 1-M, revamped for 2018, features the PWS long stroke piston system originally designed for the AR-15 platform. What makes a short gun run, makes a long gun accurate- that being said, the MK2 is among the most reliable and accurate in its category. The MK2 line features a free-float MLOK handguard with fully forged upper and lower receivers. Lightening cuts and an eliminated forward assist make the MK2 MOD 1-M line a lightweight yet solid feeling firearm. Accuracy, smooth operation and reliability make the MK2 MOD 1-M line a necessity for those looking to expand their long-stroke piston system firearm collections. The MK218 MOD 1-M offers shooters a long range gun with the convenience of a semi-auto platform. Coming standard with a PRC30 compensator on the end, the MK220 MOD 1-M is the ideal firearm for quick follow up shots at long distances.
