Milled from 7075-T6 billet aluminum, this design brings forward the current focus to modularize weapons systems for ease of future upgrade, standardize parts and common part dimensions for interchangeability with foreseeable developments and most importantly provide the modern warrior with an improved degree of familiarity when changing weapon models and tactics in all future battlefield scenarios. To summarize, what we are seeing from our perspective is the battle-proven Remington Model 700 (military designation M40, M24) being upgraded to the reliability and handling characteristics of the M16 / AR15 platform. You'll see many more modular-sniper type accessories being released for commercial sale on our site soon.

The assembly itself is one seriously rugged unit, cnc machined and hard-coated black. The extended latch assembly looks very rugged, the latch itself could be filed down if the experienced operator determined a shorter throw is desired. I like it where it is as it is quickly able to be engaged with the trigger finger, dropping the "empty" and the AR-Type magazine funnel seems to find the fresh mag on its own and suck it right into receiver with no fear of error or misalignment. Therein lies the advantage over previous "flush-bottom" systems - one can stay more easily target-engaged during a stressful drop 'n swap reload.

For those that prefer the more traditional, flush mounted magazine port, we are now offering both versions. Funnel or no funnel they take the same magazines, and are available in both long or short action versions.

NOTE: STANDARD 700 BDLSTOCKS MUST BE FITTED TO THE "M5/BADGER DM" INLETTING FOR THIS SYSTEM, IT'S THE SAME INLETTING, TAKES THE SAME AICS-TYPE MAGAZINES, JUST AN IMPROVED DESIGN. AS WITH ANY DETACHABLE MAGAZINE SYSTEM, THE PILLAR-HEIGHT IS CRUCIAL FOR MIL-SPEC RELIABILITY, SO WE INCLUDE THE PILLARS AND THE SCREWS TO PUT IT ALL TOGETHER IF YOU ARE MODIFYING YOUR STOCK. (Of course, you can simply measure the height of your existing pillars (1.075" rear / .720" front) and adjust if required. Any adjustments should be made from the bottom of the stock as the M5 mil-spec hardware is a tad thicker than the standard 700 floorplate.)

If you are installing this in any stock that was not originally designed for the M5 inlet, such as your factory or aftermarket stock, you may be weakening it at a critical location or otherwise risk damaging the stock by installing it, only a qualified gunsmith can advise you on this. WE specifically DO NOT RECOMMEND USING THE M5 IN A BELL & CARLSON, H-S PRECISION or any aluminum bedded composite stock for that matter until the stock maker inlets them to fit.

The M5 military/police metals are significantly deeper and wider than the factory cut. This may seem obvious, but we cannot be responsible for functioning in someone else's inletting job. The person doing the stock modification (we strongly suggest using an experienced Rem 700 Tactical gunsmith that has done them before now) is solely responsible for functioning. Before purchasing for such use in a standard stock, Stocky suggests you select the M4 DM System as it is a drop-in for most BDL's, VTR's and SPS's. FYI, we carry several Manner's Composite stocks as well as McMillan Stocks that are designed and pre-cut for this metal and are highly recommended over modifying any other stock we are aware of!

Accuracy International is frequently out of magazines but I have been testing the Accurate-Mag brand also and they work great also. We use them ourselves interchangeably. Again, I highlight the fact that these are tactical, military spec conversions, therefore there is some rattle possible particularly when the magazine is empty. This is so the warfighter can crawl through the mud and sand and it will still most likely continue to function even when dirty.

Stocky's take: We now offer both versions, one with and one without the lower extension (magazine funnel) for those that have a preference. Same construction, same mags, only the bottom is different.

Note on cartridge interchangeability - When inspecting an AI-style magazine you may notice two vertical ribs stamped into each side of the magazine. The front one is designed to limit the forward travel of the loaded cartridges under recoil by contacting the front of the cartridge shoulder. This is the limiting factor on interchangeability; if the shoulder of your intended cartridge is farther forward than the base round (i.e..300 Ultra Mag in the .338 Lapua magazine) it will not fit because the case will contact the rib, preventing them from being loaded. This means the .30-06 and 7mm Rem Mag families will be fine in the .300 Win magazines, the .243 has the same shoulder location as the .308 Win, etc. Compare shoulders NOT overall length when ascertaining interchangeability.

Binder Plate Details:

  • The magazines with front binder plates are compatible with all rifles equipped with AICS-pattern bottom metal or chassis systems.  The binder plate holds the cartridges back from the front of the magazines and guides them past the bottom of the feed ramp.  The maximum cartridge overall length (COAL) that will fit in this magazine is 2.870”.
  • The magazines without front binder plates allow a maximum cartridge overall length of 2.960”.  These are compatible with all AICS-pattern bottom metal and chassis systems, but most common actions such as Remington 700 and Savage 10/11 will require modifications to the receiver (i.e. notching out the bottom of the feed ramp) to prevent the bullet tips from catching on the bottom of the feed ramp (see photo below).  DO NOT order these magazines without a full understanding of this.
