The Magpul PC Backpacker Stock for Ruger PC Carbine allows your PC Carbine to break down into 2 pieces for easy transport and storage. The Backpacker Stock utilizes an innovative locking mechanism that attaches the barrel assembly to the receiver that allows you to detach the barrel and carry or store the rifle in a backpack without compromising accuracy. It's made from Magpul's advanced polymer and features an ergonomic handguard with M-LOK slots at 3 and 9 o'clock positions as well as interchangeable cheek risers to accommodate various optics. The stock features the proven MOE SL rubber buttpad, which provides an anti-slip surface that absorbs recoil.
