The Lumley Arms DBMs are CNC machined from one piece billet. Aluminium is avoided completely, however we do include bedding pillars which are machined from 6061-T6 then anodised. All minor components are 316 stainless steel, including the spring, roll-pin, lever (only on 316 version), and action screws. The stainless roll pin and action screws on the 4140 QPQ version are zinc plated black in colour to match the QPQ nitriding of the lever and DBM body which is matte black.

The Lumley Arms DBM is machined to fit the Remington 700 Short Action.

This is the 4140 nitrided steel version.  It is constructed out of high quality ordnance-grade steel and then nitrided using a QPQ salt bath nitriding process that raises the surface hardness to 65 Rc with a matte black colour.

The steel units for the Remington 700 short action weigh roughly 250 grams (0.55 pounds). Although just over twice as heavy as an equivalent alloy unit of around 110 grams (0.24 pounds), the difference is negligible when weighing up the added benefits of using these high grade steels. Specifically they won’t chip like anodized aluminium does when a hard impact is encountered and the teflon coated AICS magazines slide in and lock up with very little resistance or abrasion unlike aluminium where the anodising wears off over time in the key friction points.  Considering most rifles that these are destined for tend to carry large telescopic sights, heavy / bull barrels and tactical / varmint stocks, the extra quarter pound or so in weight for a quality steel DBM in our view is insignificant.  If you have access to one of our units, check the differences for yourself before deciding on which option to go for.
