Lumley's high-quality bottom metal replacement for the original plastic version at a very competitive price. Fully CNC-machined from a mix of high-grade titanium and aluminum alloys with absolutely no cheap 6000 series aluminum alloy used anywhere. The development of this bottom metal replaces the last chunk of plastic that comes with the factory rifle. This results in a very strong, lightweight, and corrosion-resistant product - providing the perfect bedding platform for your T1x rifle. Bedding pillars and hex-head action screws are included.


  • Very lightweight - weighs under 3.11 oz (88.2 gm)
  • The body of the DBM is machined from high-grade 7075-T76 aluminum alloy
  • The trigger guard is machined from aerospace Ti6I4V titanium alloy
  • Accepts all T1x magazines
  • PVD finished Ti trigger guard
  • Milspec Type III hard coat anodized body
  • The trigger guard is fully replaceable and serviceable
  • Includes bedding pillars and non-tapered hex head screws - both 316 stainless

Stock Compatibility:

  • The factory walnut stocks (hunter) will in most cases drop-in and require either no fitting or very minor fitting.
  • The factory synthetic stocks (MTR) are not usually a drop-in fit due to the poor tolerances involved with the molding process employed to manufacture these stocks. The bottom metal will generally press in by hand however some force may be required and in some cases, the DBM will need to be tapped in using a nylon block and nylon-tipped hammer. More details in the fitting guide section below and the PDF linked below.
  • The factory fiberglass (UPR) stocks have a different inlet pattern for the bottom metal. The Lumley bottom metal will fit the UPR stock however there will be gaps on either side which are cosmetic, not functional.

Fitting Guide:

Installing this Tikka T1x DBM follows the same process as the T3/T3x DBM. The Lumley T3/T3x fitting guide is available to download in PDF format (with step-by-step photos) here.

  1. The Lumley DBM is 100% identical to the factory inlet. They measured a number of OEM synthetic DBMs to determine the correct inlet profile. Don't rely on your particular stock being exactly within tolerances correct, particularly if you have an OEM synthetic stocked rifle which may require up to 1mm of material removed from the inside surface adjacent to the magazine well (see image in the photo gallery of this surface marked by red arrows. It is the step inside of the stock only - not the inlet for the DBM).
  2. The Lumley DBM does not require any modification to the stock aside from drilling the action screw holes out to 10mm to fit the pillars (if applicable). They recommend using a 9.9mm drill bit to begin with.
  3. In almost all cases the DBM is a drop-in fit for the OEM Hunter and UPH stocks.
  4. The OEM synthetic stocks (MTR) have poor tolerances due to shrinkage after molding. When fitted to these stocks, the DBM in most cases will need to be gently tapped into the inlet.
  5. It doesn't take long to fit this DBM and have it functioning reliably. Contact us first if you are having difficulty. We do not recommend making any modifications to your stock inlet, magazines, or the DBM.
