Bump

i emailed caa, primary arms and started a thread about them. just got a response from pa. wont work with suppressor sights or a can. threaded barrels may work in some cases. that said what info i did find was that some clearance work inside the frame will fir a read sight but not the front. some guys got threaded barrels to fit after removing the thread protector. i saw a few where guys dremmeled the front of the chassis and used a longer threaded barrel to clear a can
