Finally, a high-quality bottom metal replacement for the original plastic version. 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 T3 or T3x rifle.

  • All other components stainless steel (either 304 or 316 grades)
  • Drop-in fit replacing the original factory plastic trigger guard
  • Accepts all T3/T3x factory magazines (NOT compatible with CTR magazines)
  • Available in two colors (with slight variations between Al and Ti components)
  • Silver/grey color - garnet blasted finish to Ti parts, silver anodized body
  • Black color - PVD finished Ti parts, Milspec type 3 hard coat anodized body
  • Trigger guard is fully replaceable and serviceable
  • Includes bedding pillars and non-tapered hex head screws (both 316 stainless)'
  • Weight: 83.4 gm (2.94 oz)

Fitting Guide:

  • This DBM follows the factory inlet 100% and does not require any modification to the stock aside from drilling the action screw holes out to 10mm to fit the pillars (if applicable).
  • In most cases this will be a 'drop-in' or 'push-in' fit for factory timber or laminate stocks - however, please note factory tolerances vary which can cause fitment issues for some rifles.
  • The factory synthetic stocks have very 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 (cover with a soft towel and use a nylon tipped hammer).
  • The Lumley Magazine Release Lever is designed to lock the magazines up tight. The plastic original is typically shorter by up to 0.5mm to 0.75mm than it needs to be (varies based on the degree of wear/distortion from use). This sloppy tolerance is partly why the tension spring is there to take up the slack. Due to differences between individual magazines, the top of the Lumley lever may need to be shortened between 0.5mm to 0.75mm for your particular rifle and magazine(s). This is quickly and easily done by just 4 or 5 firm swipes with a metal file (with the lever removed from DBM and secured in a vice).
  • The Lumley DBM is very rigid - whereas the plastic original is not. For this reason, the factory tension spring is rigid (0.5mm thick) and excessively angled pushing the magazine forward to counter the flex on the factory plastic parts. This causes problems for some customers with the magazine not clipping into the Lumley DBM unless it is pulled backward against this tension spring when inserted. To correct this spring tension, remove it from the trigger housing (5mm Hex Key required) and reduce the angle closest to the screw hole to 90 degrees by bending it whilst clamped in a vise.
  • Don't rely on your stock having the correct spacing between the action and DBM at either the front or rear action screws. Use the provided pillars or measure the tangs (front: 22.7mm/0.8937" and rear: 33.02mm/1.3"). Test fit the DBM to the action first using only the pillars and action screws (no stock) to check magazine function.
  • The previous three steps account for virtually 100% of fitment issues. It doesn't take long to fit this DBM and have it functioning reliably. Contact us first if you are having difficulty before making any modifications to your stock, magazines or the DBM!

This is a superior unit. The bottom plate is a superior grade of aircraft aluminum, and the bow of the trigger guard is titanium. It does not have the squared tactical profile common to some bottom metal for Tikkas, but rather, it keeps the more graceful, rounded profile of the factory plastic. One of the most exciting aspects of this replacement is that new action screws and ferrules were included so the new bottom metal’s rigidity will be complimented by pillar bedding. The cost is among the lowest of any replacement bottom metal for the t3x. I believe it represents an excellent value and an upgrade to function, accuracy, and aesthetic for your Tikka.

I think this is the best enhancement available for the money for a rifle with everything otherwise well-designed and well-made.

5 stars!
