Premium Design and Manufacturing Features: The Mk-1 DBM bottom metal hardware features chamfers and bevels on all external and internal edges that can come into contact with your hand, your magazine or your other gear. No sharp edges like found on economy DBMs from other sources. Including this simple design feature correctly on the finished part means utilizing more expensive CNC equipment and a little more process time per part but we absolutely believe it is worth the effort.
I believe we have struck a very good balance between premium features and pricing.
Maximum Z-axis control of your magazine: The Mk-1 keeps all of the pertinent design elements of the SENTINEL magazine well. This includes using all available means to support the AICS and AW magazines without holding the magazines so tight that insertion and removal are a pain.
From the beginning my thoughts were that if the magazine itself is going to protrude from the bottom of the rifle then the magazine well should protect it and would not be anymore obtrusive than the magazine body.
The increased Z-axis support means that the shooter is less likely to induce a feed failure because the magazine is controlled better. Having the front of the magazine well extend below the stock belly also helps insure that the magazine is not damaged or put in a bind when pushing against rails, barricades or other hardpoints used as a rest in the field or competition.
KMW was the first to incorporate the extended depth magwell in a DBM hardware set. Since then several other makers have copied the lines and design of the extended mag box in their own "NEW" products.
Low Profile Ambidextrous Magazine Release Latch : Just like the SENTINEL DBMs, the Mk-1 latch is very conformal and protected compared to a many latch systems. This design minimizes snag points and decreases the likelihood of accidentally releasing your magazine during movement or transporting. KMW was the first to incorporate a T- shaped release latch.
Premium materials and coatings : All Mk-1 DBMs are machined from 6061-T6 aluminum. After passing inspection, they are processed with a premium Mil-Spec anodizing. This anodizing is a true MATTE via aluminum oxide surface prep prior to hitting the tanks and it is a true Hard Coat specification. The magazine latches are machined from tool steel and processed with a black oxide finish.
Well established inlet : The Mk-1 DBM utilizes the same inlet footprint and pinch-points as the KMW SENTINEL DBM and the Surgeon Short Action DBM which was based off of the KMW hardware.
Weight: The Mk-1 DBM assembly weighs 4.58 ounces or 129.5 grams without pillars or stock bolts.
What it comes with : Each Mk-1 DBM bottom metal hardware set comes with pillars machined from 6061-T6 to the correct length to insure proper function with Remington M700 and all similar custom versions. Made in USA grade 8 stock bolts from HoloKrome are inlcuded. The Mk-1 is not priced or packaged with magazines due to the number of variable caliber and style variations that you could build to.
WHY did I develop the Mk-1 DBM ?
I have seen a need for a full featured premium DBM for a competitive price.
On one hand, I have continued to see individuals build custom rifles with very expensive components and coatings then get the least expensive DBM they could find. While cost does not always equate to features and quality , it usually* is proportionate. What I see with most of the least expensive hardware is the lack of features built into the design. Machining a part on a CNC machine that cannot turn the part for chamfers and other features mean that the finished part will have a lot of sharp edges for your hands, your gear and even your magazines to negotiate around.
I am very glad that the lower cost, lower feature alternatives are out there. Their existence insures that shooters on tight budgets have a DBM choice that they can fit into their finished price point. This choice is crucial to the expansion and the growth of our shooting niche.
While I absolutely support individual choice and proliferation of many product candidates on the market, I personally find it amusing when a person cuts corners on key components while otherwise giving free reign on every other aspect of the new rifle project. It's the same as people that purchase a $3,000.00 optic and then mount it in some $15.00 rings and expect it to not have issues when used hard.
On the other hand, I have seen some previously premium hardware being sold at premium prices while their quality control and finish specifications have dropped terribly. Sometimes you do not get what you pay for.
HOW did I develop the Mk-1 DBM ?
My SENTINEL stock uses a DBM that I designed at the same time the stock was conceived. Because that DBM conforms to the bottom lines of the SENTINEL stock, it cannot be fitted to conventional A-Series (McMillan) or T-Series (Manners) tactical and competition stocks with flat bellies/bottoms.
Since the DBM on the SENTINEL series is well established and has an immaculate track record, I chose to keep everything pertinent to function and reliability intact.
By simply removing more material around the front stock bolt and behind the trigger guard, the SENTINEL bottoms will work perfectly with conventional stocks. The new Mk-1 DBM even uses the same manufacturing fixtures, mag latch, latch spring and latch pin as the parent DBM. The pillar length (pinch point) is the same and the footprint inlet is already on file with most custom stock makers inside the U.S.
The primary business of KMW is building precision field rifles. KMW is a small boutique shop and my business model is not set up to efficiently handle high quantities of individual orders.
While KMW will always be your primary contact for any issues or failures you may experience with this hardware, I encourage you to contact one of the distributors or builders listed below if you would like to order a Mk-1 DBM hardware set.
