The BLR actually two different rifles.
One is the original steel receiver for short action cartridges.
An intermediate version is the BLR-81. Steel receiver also.
Second is the long-action aluminum only receiver in full length cartridges to include 7mmRemMag and .300RemMag.
Mine is a .358Win. Quite accurate off a bench, but atrocious trigger limits it’s usefulness.
It’s also too pretty to hunt with. But it’s a killing machine. Three shots, three dead deer, right there...
I had to replace the original butt pad with a Boyd’s 1/2” pad. It dramatically reduced weight, length of pull, and improved fit/handling of the rifle.
The long actions (there are also short actions w/aluminum receivers, and take-down models) but long actions all have pistol grip stocks and are unwieldy. IMO.
My gun, except for a 2-7x Leupold, is a clone of Nature Boys.
Be aware, my 4 magazines are worth much as the gun is. And aren’t compatible with newer rifles...
