Assisted by his colleagues at Spectre Inc - Wolverine Supplies Founder, John Hipwell produced a new concept...the WS-MCR.

Here is what John himself had to say about the new design...

"I like the original AR180 concept, so we went back to her and started fresh. We stayed with the modern CNC aluminium lower receiver, I believe this was first produced by Nodak Spud as the NDS-18S and was introduced to serve as a direct replacement for ArmaLite’ s polymer lower. No need to reinvent the wheel, so we used that lower although we did add one very major improvement. We built in a rear take down pin, this eliminates the movement often found between the upper and lower. This pin also strengthened and stiffened the complete rifle.

Again, looking at the original AR180 rifle, we followed their lead and in the new WS-MCR we once again have both the cam pin and the charging handle travelling on steel. To achieve this, we added two steel plates; one inserted on each side of the upper receiver. This added to the cost, but we consider the advantages well worth the extra expense. We also carried out some improvements to the bolt carrier. This resulted in a much smoother action and has minimized the wear associated with a hard steel component running on soft aluminium.

We are introducing the new WS-MCR rifle in three calibres; 5.56 NATO, 7.62 x 39 and .224 Valkyrie. This meant we had to revise the gas system, again this is different to anything that has been marketed to date. We have spent several months fine tuning the gas system and this has resulted a soft positive ejection.

Another new feature not found on any previous production rifle of this general type is that we have added a case deflector. After several thousand rounds, we have avoided the ugly scarring that ejected cases can inflict on the receiver.

The hand guard which is free floating features a 1913 type accessory rail on the top. We have chosen a long 15 inch handguard, which features a locating pin and is simply clamped around the barrel nut with three large allen screws (4mm). The handguard will be required to be slipped off in order to clean the gas system. The gas cylinder plug requires a standard ¼ inch wrench or socket for removal.  Any further disassembly or modification may void the warranty. The WS-MCR will have a 12-month warranty which will cover defects in materials and workmanship. This will be administered directly by Wolverine Supplies.

The barrel nut only needs a 1 1/8th inch wrench, no specialized tools are needed for disassembly of the WS-MCR, although I would recommend using an AR15Lug-Lok upper vise block if you intend to remove the barrel. These need to be slightly modified to fit the WS-MCR receiver."
