A Tale of 4 Piston Rifles
This review compares four piston-driven AR-style rifles: PSA Jakl, Foxtrot Mike FM-15, Brownells BRN-180, and PWS MK109 Mod 1-M. While piston systems offer advantages for suppressed shooting and reliability, they often come with weight penalties and proprietary parts. The PWS MK109 Mod 1-M is highlighted for its superior reliability and performance, especially when suppressed, making it the top recommendation.
