The much anticipated UHP15-PDW Lower/Stock system is finally here. Cross Machine Tool just shipped the first units to Rainier Arms which should be arriving any day. This is a very high quality ambi billet lower that also includes an improved PDW style stock and Cheek Rest with many patent pending improvements. You can use any BCG you want as well which is a nice upgrade. If you are looking for a special lower to build an SBR with, something that not only is better than other designs but very limited in availability as well, this is for you. If you’re trying to build an SBR on a budget, you might as well just keep scrolling.
Pre-Orders are not usually something that Rainier Arms offers but with the limited availability and huge interest that is what they are offering. This first shipment should be in and shipping out to those who pre-order by June 23rd. Pre-order now at www.RainierArms.com.
The UHP15PDW Lower receiver features the Integration of a Patent Pending Monolithic adjustable PDW type stock system. This Patent Pending Monolithic stock/lower receiver design is the result of a collaboration between BattleArms Development & Cross Machine Tool. The UHP15PDW lower also includes the Ambi Bolt release & Ambi Mag Release Lever similiar to the UHP15A lower receiver. The Ambi Mag release Lever is designed to work in conjunction with the Standard Mil-Spec Mag catch arm without the requirement of proprietary components for proper function. This mag release lever design provides the user field repair options of the mag catch typically not found with most ambi mag release systems that utilize proprietary mag catch arms. The Ambi Mag Release features a raised fence on 3 sides to protect the mag release from accidental actuation during weapon use. The Bolt release Lever & Mag Release Lever feature aggressive Texturing to ensure proper finger placement & grip during actuation. The ambi bolt release, ambi mag release & buttstock adjustment rods are Black Nitrided for corrosion protection. The Integration of the stock rod system with the lower receiver creates a stonger continuous PDW platform & also allows for the addition of a cheek weld that extends with the buttstock not currently found with bolt on PDW stocks due to the bolt on housing design that extends rearward over the buffer tube.- 5 AXIS CNC MACHINED FROM 7075 T6 BILLET - TYPE III CLASS II ANODIZED BLACK - WIRE EDM MAG-WELL PROFILE - .154” DIAMETER REAMED TRIGGER & HAMMER PIN HOLES - MULTI CAL MARKED - INTEGRALLY MACHINED TRIGGER GUARD - 3.3oz TUNGSTEN WEIGHTED BUFFER W/SPRING - INDUSTRIES SMOOTHEST WIRE EDM CUT FLARED MAGWELL, COMPATIBLE WITH USGI AND MAGPUL GEN 2/3 MAGAZINES - NO ROLL PINS NEEDED FOR ASSEMBLY - UPPER TENSIONING SCREW - BOLT CATCH ASSEMBLY SCREW - LIFETIME WARRANTY AGAINST MANUFACTURE DEFECTS - AMBI BOLT RELEASE/ HARDWARE - AMBI MAG ARM RELEASE LEVER - PATENENT PENDING INTEGRATED 4 POSITION STOCK WITH 4 INCHES OF PULL - PATENT PENDING PDW STOCK CHEEK WELD - PATENT PENDING PDW INTEGRATED STOCK ROD LINEAR BUSHING GUIDANCE SYSTEM - PATENT PENDING STOCK BALL LOCK MECHANISM - COMPATIBLE WITH STANDARD LOWER PARTS KITS - WEIGHT COMPLETLY ASSEMBLED- 2LBS 4OZ.
