Product Info for Primary Weapons Systems MK1 MOD 2 Upper Receiver

The Primary Weapons Systems (PWS) MK1 MOD2 Uppers are forged, allowing for a much stronger and lighter product than a billet part. The MOD 2 handguard is equipped with the PicMod Technology. This allows you to mount any MLOK attachment anywhere on your rail while being able to mount most Picatinny accessories directly to the rail in the areas where the PicMod feature is present. This gives you the most mounting options without having to use MLOK mounted Picatinny rail sections, adding unnecessary width and weight to your rifle. The PWS MOD 2 Upper is equipped with an adjustable gas block that has three easy to use settings. Everything about the MOD 2 has been designed to be an incredibly accurate fit and finish. Available in 3 different barrel lengths and two calibers.
