Roller-Delayed Blowback

The SP9A3S uses a semi-locked bolt delayed by a transfer roller, with internals designed to run reliably with the short 5.5" barrel. The non-reciprocating charging handle stays forward while firing.

Enhanced Adjustable Stock

The Enhanced stock adjusts for length of pull so you can set a consistent cheek weld and shoulder position. Because this is a factory SBR configuration, the stock ships installed.
