The SierraPapa Steel Guide Rod replaces the stock plastic guide rod with an unbreakable steel rod, and guarantees absolutely reliable function of this critical part. Improved push-fit attachment to the plastic buffer reduces assembly/disassembly damage, and the recoil spring conveniently stays in position on the guide rod for cleaning and disassembly of the bolt group.

This Steel Guide Rod uses our High Durability Buffer for longer buffer life and improved performance, and accepts our bronze Bolt to Recoil Spring Link for life-long reliability.
