With all the stock, action, and bottom metal choices on the market there is a lot to digest when picking the right bottom metal for your rifle. To help navigate the process for your next hunting, competition, service, or fun gun build we have compiled this article on how to pick the best bottom metal from our product line-up. (We will update this article as new bottom metals and developments arise.)
First let’s talk about Detachable Box Magazine Bottom Metal.
M5 DBM (Detachable Box Magazine)
Hawkins M5 DBM is designed to fit into stocks with an M5 inlet. They are precision CNC machined from a single piece of billet aluminum, incorporate a barricade stop, and have a patented cantilever spring release that will not open under heavy recoil.
These are made for Remington 700 and custom 700 pattern clones. (Impact Precision, Lone Peak Arms, Defiance, Zermatt Arms/Big Horn, Stiller, Curtis Customs, Terminus, Kelbly, Surgeon, American Rifle Company, Borden, Pierce Engineering, Vudoo, RimX, etc.)
Short Action DBM: The short action M5 DBM is made for use with AICS magazines, but will work with AW magazines if your action is cut accordingly. Please select our LA Latch/AW version of you plan on strictly running AW magazines or are using a 22LR. The latch is taller and helps the magazine ride higher in the magazine well for better feeding. Accurate & MDT 223 Magazines, and Vudoo Gunwerks users will also want to pick our AW/LA latch version.
Long Action DBM: These feature the same features as our short action bottom metals. They are made for long action magnum and standard calibers with AICS magazines. (300 Win Mag, 7 Rem Mag, 30-06, 280AI etc.)
XM DBM: Hawkins Precision makes bottom metal for both the Lone Peak and Defiance XM footprint. For Defiance XM use MDT XM magazines. Contact Lone Peak Arms about XM Oberndorf style bottom metal for the Lone Peak foorprint. (Calibers: 6.5 SAUM, 7 SAUM, 300 WSM, 6.5 PRC)

338 CIP+ Length Notes: Designed for use with Accurate Magazines with a magazine overall length of 3.850”. (.338 Lapua Mag. SSSF Magazine or Accurate 300 RUM magazine) For use with long action stock inlets. These will also work with 3.850″ MDT Magazines. Please note this is the outside dimension of the magazine. Internal COAL is 3.760″ for MDT / 3.750″ for Accurate.
M5 Oberndorf Bottom Metal
The Hawkins Precision M5 Oberndorf Bottom metal is the perfect solution for anyone looking for added modularity in their rifle system. This is a hinged floorplate bottom metal designed for an M5 inlet. Running this bottom metal allows the user to have numerous stock options while still having a BDL style bottom metal.
They feature a reversible and adjustable mag/floorplate catch and have a thicker floorplate that creates less spring pressure, providing added reliability when loading Ultra Mag cartridges.

Please Note: When ordering your stock ask for a Hawkins Oberndorf inlet. The Oberndorf profile is not the same as a Remington 700 BDL. An Oberndorf bottom metal will fit inside a stock with BDL inlet, but it may not fit perfectly. Some fitting may be needed. If you’d like a perfect fit, order an Oberndorf inlet from the start.
