The 7mm VALKYRIE was designed to be one of the most powerful hunting rounds for the AR-15 platform. In order to do that the 7mm VALKYRIE uses a proprietary bolt/barrel extension that are sold with the barrel all other standard AR-15 parts are used.
The remainder of the rifle is all standard AR15 rifle components. To be clear, the 7mm VALKYRIE uses standard, readily available AR-15 upper receivers, bolt carriers, buffers, buffer springs, stocks, gas blocks, barrel nuts, hand guards and lower receivers without modification.
The 7mm VALKYRIE works best with 6.8 PRI magazines because they allow 2.31 oal and they are stiffer so they don't bulge when loading. Some of the longer and heavier bullets require an oal of 2.34 inches which requires a notched magazine which will limit capacity to 5 or so rounds. Other 6.8 and 6.5 mags work but capacity is limited because of the mag swelling when loading. Typically around 4 rounds in the asc 6.8 mag and the cproducts 6.5 mag from my testing.
