I got my new 50 going recently, she uses my old Barnard GP action from my 416 Barrett, she is essentially a switch barrel now, I can easily put the 416 barrel back on her :)

She has a 34" Trueflite barrel, Dolphin Chassis, T6 Terminator Muzzle Brake.

I'm very happy with the brakes performance both with recoil reduction & lack of aggressive concussion which effects many effective 50 brakes.

After initial testing accuracy looks pretty good & I'm looking forward to stretching her legs :cool:

Gotta love a 50 :thumbsup:
