We have a small stack of brand new, unused Colt .223 extractors for the AR-15 series. We use Colt bolts for the .458 SOCOM uppers and replace the Colt extractor with a different one, so that is where we end up with these. $15 each shipped to address of your choice
Also have an unused Jerry Miculek screw on brake/comp with indexing nut. Fits standard .223 threaded barrel. $50 shipped.
