PRIMARY WEAPONS MK111 PRO 223 WYLDE COMPLETE UPPER RECEIVER FOR AR-15


The PWS MK1 PRO line features the PWS long stroke piston system. This line is perfect for shooters looking for a cost-effective piston system firearm without sacrificing the high quality standards PWS has been known for over a decade. Featuring a 3-setting adjustable gas system for users with suppressors, free-float MLOK handguard, Radian Raptor charging handle, extruded upper receiver that integrates an extremely solid handguard attachment system, the MK1 PRO line has an assortment of features ideal for shooters of all levels. Available as a complete upper or complete firearm (both pistol and rifle configurations). As with all PWS complete upper receivers, they will fit seamlessly to any AR15 lower receiver with no need for add accessories. The PRO line is the best value on the market when it comes to piston driven operating systems, including high-end features and custom components. Adding to the overall value, the entire MK1 PRO line comes with the same performance expectations and lifetime guarantee as all PWS products.


The MK111 PRO upper features an 11.85” barrel, the idea length for a variety of uses. From pig hunting to home defense, this pistol is a go-to for all uses, including suppressed shooting. Fitting any standard AR-15 lower, this can be matched with a registered NFA or pistol lower to allow shooters to take their shooting to a new level.
