I am looking at buying a SAKO TRGS NIB for less than 500$ in 7mm rem mag. How long is the barrel? How are these discontinued guns, GOOD SHOOTERS, RELIABLE? Does it have a fixed ejector or plunger? How does the stock compare with the 75 synthetic in terms of stiffness? How is the detach mag? DOes it have the same release as the 75? ANYONE WITH FEEDBACK PLEASE REPLY..
