SKU: M6-B-Seconds Category:

Mounts sold under this category are discounted because they have minor blemishes (this kind of merchandise is also referred to as “seconds”). They have flaws that are cosmetic, but do not impact the mount’s functionality. Each blemished mount has its own imperfections, which may include small scratches, pitting in the anodizing finish, and slight discoloration of the finish.

The photos above showcase the possible flaws one can expect to find on these particular M6-B mounts. The closeup photo shows a typical scratch within the red circle, and the pitting is prominent within the anodized finish of this particular specimen. The last photo shows the slight discoloration that may be present.

Taking the versatility of the M1 Carbine to the next level, the UltiMAK model M6 mount is the lowest, most stable and practical optic mount available. The forward positioning allows faster targeting with better field of view, provides more rail length, maintains full access to the receiver mechanism with optics in place, and will not interfere with case ejection. No need to remove your rear iron sight. Use of Q.D. type scope rings (Aimpoint 12243 shown, bottom left) allows you to revert to full functionality of iron sights while your UltiMAK M6 mount remains in place.

The MIL STD 1913 (Weaver/Picatinny) rail sits lower than anything else available for this great carbine, providing a better, more natural cheek weld for extremely fast target acquisition. No-gunsmithing installation (some stocks require minor inletting [removal of some wood or plastic] inside the forend, while the old G.I. stocks we’ve tested require no modification). CNC machined from super strong 6061-T6 aluminum and hard anodized.

* Additional notes on compatibility:

The UltiMAK M6 optic mounts are designed for MIL SPEC carbines ONLY. They will not fit, and cannot reasonably be modified to fit, most commercially produced Carbines from the 1960s, ’70s and ’80s, such as Universal, Plainfield, Iver Johnson, National Ordnance or Alpine. If you have one of these non-MIL SPEC Carbines and you want to enjoy the benefits of the M6 UltiMAK System, it is advised that you trade your Carbine for a G.I. blueprint Carbine. Either a 1940’s vintage or the more recent production IAI or IMI (M6-B), or a new Auto Ordnance Carbine or the new Inland Manufacturing Carbine (M6-Sa). It will likely perform better, and will be compatible with after-market parts, stocks and accessories. A VERY FEW of the early production commercial Carbines from the late 1950s and early ’60s do have MIL SPEC barrels (they were assembled from GI surplus parts), and so it is up to the user to determine which barrel one has before ordering a mount for one of the old, commercially produced Carbines (again: Universal, Plainfield, Iver Johnson, National Ordnance or Alpine). We will of course take returns for refund if a mount ordered from us simply does not fit, so your only risk is the small shipping charge and a little bit of your time.

To summarize; MIL SPEC Carbine? We have a mount for it.
Non-MIL SPEC Carbine? We do not have a mount for it.

All newer production MIL SPEC Carbines (IAI, IMI, Auto Ordnance and the new Inland Manufacturing), even though they may be GI spec and compatible with one of our M6 mounts, WILL need to have wood removed from inside the stock forend to accommodate the UltiMAK barrel clamps. See the installation instructions, Figure 9 and accompanying text, at the link below. Again; with extremely rare exceptions, the original, 1940s production stocks are compatible and will provide for a true, “drop-in” (no modification) installation.

An UltiMAK M6 optic mount, when installed, should touch nothing but the barrel (should not touch the barrel-band, the stock, or the receiver, and the UltiMAK barrel clamps should not touch the stock)(see close-up photo below).
