SA5 Pro Folding Stock Adapter

The SA5 Pro folding stock adapter is CNC machined from 4140 steel, providing 250 percent increased strength over the Gen4 adapter. Right fold design reduces overall length for storage and transport. Adjustable tension hinge allows customization of fold tension while the improved locking mechanism secures the adapter when deployed. Two integrated QD mounts provide sling attachment points. Standard 1 3/16 x 16 threading fits mil spec AR-15 buffer tubes and most AR-10 builds. Includes 1045 steel bolt extension for use with standard AR-15 BCGs. Compatible with 9mm BCGs with .625 internal diameter after removing rear pin and weight. All installation tools included, installs in under five minutes without additional parts.

9mm Magwell Adapter

The Sylvan Arms 9mm magwell adapter is machined from 6061 T6 aluminum with black finish. This adapter converts standard AR-15 lower receivers to accept Glock pattern 9mm magazines. The magwell adapter installs in the magazine well and enables use of widely available Glock compatible magazines without permanent modification to the lower receiver.

9mm Nitride Bolt Carrier Group

The bolt carrier group is constructed from 8620 alloy steel with nitride finish. External extractor design provides reliable extraction across various ammunition types. Nitride treatment penetrates the steel surface rather than coating it, maintaining dimensional tolerances while adding wear resistance and corrosion protection. Pistol caliber design optimized for 9mm blowback operation.

PMAG 15 Round Magazines

Three PMAG 15 round magazines provide Glock G19 pattern compatibility for 9mm Luger ammunition. Proprietary high strength polymer body construction delivers durability and reliability over thousands of rounds. Stainless steel spring provides corrosion resistance and long service life. Flared removable floor plate features ridged edges for improved grip during magazine changes. Magazines drop freely when loaded or unloaded for reliable function. Easily serviceable design allows cleaning and maintenance.

Complete Conversion Bundle

This bundle provides all components needed for folding stock capability and 9mm conversion. The folding adapter enables compact storage, the magwell adapter allows Glock pattern magazines, the BCG cycles 9mm ammunition reliably, and three magazines provide immediate capacity. Compatible with mil spec AR-15 platforms.

Follow safe handling and manufacturer instructions. Verify compatibility with your specific AR-15 lower receiver and buffer system. Ensure compliance with all applicable laws including magazine capacity restrictions in your jurisdiction.
