We stock the SP223 Gen2 for builders who want a billet lower with defined control features already incorporated into the design. The enhanced bolt catch, receiver tensioning screw, ambi-bolt stop assembly, and oversized trigger guard distinguish its configuration from a basic stripped lower. Starting with a stripped receiver leaves the remaining component choices open to the builder. The SP223 Gen2 provides that foundation in a black billet aluminum format.
