Details

The Cross Machine Tool Ultra Precision Upper Receiver Part# UPUR-1LH is the perfect Mate to your UHP-15 lower receiver or would also be a great match with any Mil-Spec lower. The UPUR-1LH is machined from Billet 7075 T6 Aluminum unlike the more commonly used 6061. Using the 7075 T6 aluminum gives the UP-UR a 65% increase in strength & rigidity over 6061 aluminum receivers. The UPUR-1LH is machined on a 5 Axis machining Center to reduce the number of operations/setups required to complete. This machining process allows the highest possible accuracy to be obtained over the traditional 3 or 4 Axis machining method. The UPUR-1LH is designed for increased function, performance & to provide an advanced modern appearance & feel to the AR15 platform weapon system. The Left Hand eject of the UPUR-1LH drastically reduces the amount of gasses exiting the chamber into the face of left handed shooters when shooting suppressed.

 

The UPUR-1LH is available for order only thru Rainier Arms

This is a great looking upper. It was delivered quick. I just switched my rightly DPMS over and was pretty quick and easy, stag left handed bolt carrier group fits great and no problems so far. (Posted on 5/27/2016)

Excellent quality and fit. It is far better than the Stag Arms forged upper which is more expensive. I will definitely be ordering another! (Posted on 5/24/2016)

As a leftie, I am really excited about using this in my build. Have a couple of friends that have used this and been very happy with it. (Posted on 5/20/2016)

Being lefty puts me at disadvantage. Finding good equipment is often a real journey. Somehow I found Rainier Arms and this upper. I also own a Stag Arms lefty AR-15, but I really love this upper. I mated it with a Rainier Arms Ultra Match barrel in .223 Wylde. The upper is solid and fits my Mil-Spec lower perfectly. The barrel mounted without issue and headspaced perfectly. If you are looking to put together a lefty AR, look no further your search is over. I'm buying another for a 300 Blackout... (Posted on 10/2/2015)

This receiver far exceeded my expectation.
I own at least one receiver of every company that makes a lefty (BHW(1), SA(+5), DPMS,(1) RedX(2)). This will be the only lefty I will purchase from this day forward.
The lefty does not have a dust cover but who needs one when your spitting out shells? You provide and install the forward assist (easy) and your good to go! You wont be let down the upper has an excellent feel and nice sharp lines. The only reason I'm writting this review is because I came back for more….you guessed it they're out of stock…. :( (Posted on 5/30/2015)
