The SP 223 Billet lower feature a unique design geared towards the serious tactical shooter. The oversized winter trigger guard, quick access mag release, beveled mag well, ambi bolt drop and user friendly features make this lower the best on the market. To ease assembly Seekins Precision eliminated the use of roll pins, hammers, punches and replaced them with custom screw in dowel pins. We installed an upper tensioning set screw, a set screw for trigger reset, relocated and retained the rear take down pin detent under the grip. The ambidextrous bolt control allows the shooter to quickly drop the bolt or from either side of the firearm. The unique magwell design allows positive mag changes and allows the use of most all mags including Magpul P-mag and Surefire high capacity mags.
