MkVI Complete Upper Receiver

MkVI Complete Upper Receiver

$ 2,100.00

ETA December '15- February '16 (running behind but worth the wait!) 

Paul Leitner-Wise started LWRC (Leitner Wise® Rifle Co.) and developed one of the most successful op-rod systems for the AR in 2004 LWRC still employs this patented technology in their assault rifles to this day, but it has not changed in over 11 years. At Leitner-Wise Manufacturing, we have created new technology based on that op-rod system and have updated it to be current and modern for the patented MkVI upper receiver series.

We are constantly innovating and breaking the mold of the standard black gun. Heat destroys a rifle. The LWM piston-operated

upper receiver

is innovative because it offers a simplified design that reduces heat stress and causes less wear on the bolt carrier which prolongs the life of the weapon. When the zombie apocalypse comes and ordinary black rifles wear out, the Mark VI will still be putting rounds downrange reliably and accurately.

Everything LWM upper is billeted which is a longer machining process that results in a more reliable weapon system and you will never find a forward assist on an LWM rifle. That’s a Vietnam era holdover that just isn’t necessary.

This is an upper that is custom out of the box. All uppers come with serial numbers. LWM001 is reserved for the Warrior 360 Auction which will be in person as well as live on the internet. All other numbers will be given out on a first-come, first-serve basis. This is a piece of history. When lowers are available, we will match yours to the serial number on your upper and BCG.

Features of the MkVI upper receiver:

  • Leitner-Wise® proprietary op-rod system and gas block
  • Enhanced nitrided carrier and bolt
  • Billet 7076 T6 aluminum ambi billet upper receiver - No forward assist.
  • Leitner-Wise® contiguous rail and steel barrel nut (15" 12.5" and 10.25") that is compatible with MLOK accessories.
  • Polymer shell case deflector 
  • Hard coat anodized
  • Three extra Picatinny rail slots on upper
  • M4 style extended feed ramps
  • C3 Hybrid Compensator
  • M3 XD Extreme Duty configurable steel charging handle
  • Set of rear and front eSights
  • Laser Engraved Leitner-Wise™ logo
  • Billet dust cover
  • Leitner-Wise® fluted combat match nitrided barrel

Upper receiver

Due to high demand of these uppers, the first (LWM001) upper will be auctioned off and the proceeds will be donated to Warrior 360. 

Lifetime Warranty
