Here's my first Brno 602 which predates the Ruger Alaskan. The features are:
Ron Smith, stainless fluted .375 barrel chambered for the .375 Ultra,
A non-scalloped Ruger barrel band front sight base fitted with a brass rectangular post, the rear sight is a Talley Ghost Ring,
A custom stainless quarter rib inletted for Talley QD rings,
The rifle wears a Burris 2.75X Scout Scope,in the picture, but this was changed to a 2X Leupold EER
A McMillan Express stock with a Decelerator pad, 13.5" LOP, and the front swivel mounted to the radius of the forend tip to prevent cut hands,
A knuckle deflector was placed behind the trigger guard to prevent bruised knuckles,
The sling is a Safari Ching Sling made by Galco, this one was bought from the Gunsite Pro Shop and has the Gunsite raven embossed at the front swivel, on the ones I bought directly from Galco, the raven is missing. My second Gunsite Sling is on my Brno ZG-47.
Comparison to a pal's Ruger Alaskan:
My 13 year old grandson takes a turn, who says a .375 Ultra kicks? (300 gr cast at 1200 fps)
My current Brno 602 is closer to stock, although it wears the same McMillan stock with the knuckle deflector behind the trigger guard, has a green GunKoted action and the factory barrel was cut to 22". It has a NECG barrel band front sight with a patridge brass faced sight blade and a NECG peep sight with the aperture opened up to a quarter inch. I switch this ghost ring back and forth between the 602 and my ZG-47, although the factory express sights remain in place. And is of course this 602 is also chambered for the .375 Ultra. I don't have any good pictures of it at the moment, but you really have to pay attention to see the differences between it and a factory rifle. This one balances better than my earlier rifle, and a 270 gr bullet makes an honest 3000 fps with the same load of H-100V.
