ZRTS Threaded Bolt Catch and Spring Capture Screw Kit
These kits are a must have for those with billet lowers or a threaded (gen 2) lower. The pin replaces the roll pin that holds the bolt catch and is installed with the provided allen wrench. The set screw threads in the rear of the lower to capture the rear takedown pin sping. This makes installation of the buffer tube MUCH easier! NOTE: your bolt catch standoff must be threaded, or you can thread it 6-32. Rear screw is 4-40 and can easily be hand threaded. All stainless steel parts! Includes needed .050″ allen wrench for set screw. Bolt Catch pin is 1/16″ hex drive.
FITS AR10 and AR15 Lowers!
