FoldAR upper receivers feature a perfect return to zero: Sub 1 MOA rating and chambers are head spaced at + .002 for optimal accuracy while retaining loading/ejection reliability. Compatible with any AR-15 Lower receiver, and allows for an especially compact weapon combined with the Dead Foot Arms MCS Folding Stock Adaptor.
