The PWS MK1 MOD 1 Upper Receivers are forged, allowing for a stronger and lighter product than a billet part. Available in three barrel lengths and two calibers, the MK1 MOD 1 line offers an adjustable gas block with three easy to use settings. Equipped with the PicMod Technology, any MLOK attachment can be mounted anywhere on your rail. In addition most Picatinny accessories can be mounted directly to the rail in areas where the PicMod feature is present.
