Re: DBM why so damn exspensive??
Good luck.
I bought a 12 year old rifle, a Dakota Arms Longbow in .338 LM, last month and would like to add a DBM to it.
No dice.
I have contacted no fewer than 8 different manufacturers who have summarily told me no, there's no DBM unit made for that gun. Even the guy who built the gun, now at GAP, says there isn't one.
Here's the thing. Screw the CAD/CAM and all that, how about basic gunsmithing?
A bottom metal unit is made by at least a half dozen companies in that caliber.
How about some simple cutting and welding in an extension to make up the half inch space between a Rem 700 LA action screw spacing and the 8 inches on the Dakota and doing some simple machining to fit, make sure the base metal and magazine line up and work every time.
I haven't found anyone who is up to the task.
You haven't spoken to gunsmiths, and neither have I apparently. I can use a dremel (or a 3 axis mill) to cut and paste to fit a STANDARD unit as well as the next WECSOG gunsmith, but I don't have the welding equipment, skills, or tools and experience to make a NON-standard unit from parts. Couple hours labor, milling, trimming, fitting. Cost? It was a $3,000 rifle. Shoots fine. I just want options and would pay for them.
Rant mode off.
Like I said, good luck. Your fix sounds simple.
