The Remington M788 was made in several popular calibers including .223, .243W, .308W, .30-30W, .44 Rem Magnum.
The short barrel was standard, as was detachable box magazine. It was in production during the late 1960's thru the late 1970's.
It claimed the fastest lock time of any production bolt action, and is well-proven for accuracy.
The hardwood (birch?) stock put off some shooters, as did the multi-lug rear lockup and homely lines, but it was plenty accurate to keep owners happy. I had shooting buddies that owned them in .30-30 and .308W, and with careful cast bullet handloads, 1/2 to 3/4 MOA was routine.
Alas, since it's discontinuance, replacement parts are hard to find. A reader asked for several weeks ref a broken bolt handle with no results.
As for "Is it worth the money?", only you can decide that. Restocked and properly scoped, there is no reason not to expect the gilt-edge accuracy the design is noted for.
