I've been building Savage rifles and switching barrels for some time, using only a barrel vise and a barrel nut wrench, but I decided that the whole process would be improved if I got a rear entry action wrench. I've found two that I'm looking at but if I'm missing a better one please let me know. I already read about making sure the wrench is long enough for long actions, and I assume both of these meet that criterium.

The first one I'm considering is the Bench Source action wrench at Graf and Sons. It comes with it's own crossbar, says it does Remington 700 as well as Savage, and retails for $50 plus shipping (no free shipping to Alaska...).

The other one I'm looking at is the Davidson rear entry action wrench at Sinclair Intl. It requires a hex wrench to turn (not a problem, but it seems like a two sided lever might be easier to keep in line). This one says it is for Stolle and Savage actions, and they have a different model for Rem 700 actions. It retails for $60 plus shipping.

I was hoping someone could give me good advice here. I have to wonder why the Bench Source wrench does Rem 700 and Savage actions (preferable, since I own both), whereas the Davidson is NOT specified for Rem 700 along with Savage. The Davidson wrench is more expensive and requires an additional tool to turn it, but if it does a better job with Savage actions then I'd go with it.

Any advise from those who know these wrenches, or maybe an even better one not on my radar?
