Choose the appropriate model of M6 mount based on the make of your M1 carbine:

Model# M6-B

  • Designed to fit G.I. Pattern M1 Carbines (original USGI M1 Carbines and the Israeli IMI and IAI Carbines).
  • Length of mount: 8.055″
  • Picatinny rail has 19 slots
  • Original USGI carbines allow for drop-in installation.
  • IMI and IAI carbines require minor stock modification, but we offer quality Choate folding stocks that have been customized in-house to fit our mounts.

Model# M6-S

We are selling off some new-old stock of an earlier version of this mount called the M6-S. It is identical to the M6-Sa, except for slight differences to the shape of the underside. The M6-S mount was designed only for Auto Ordnance, as the new Inland Manufacturing carbine didn’t exist yet. If you need an optic mount for an Auto Ordnance carbine, this model works every bit as well as the newer M6-Sa. Since we’re offering the last of these at a clearance discount, it would behoove you to select this mount if you have an Auto Ordnance.

  • Fits Auto Ordnance carbines.
  • This is a slightly shorter version of our M6-B mount, and is also an earlier version of the M6-Sa
  • Length of mount: 7.812″
  • Picatinny rail has 18 slots
  • Requires minor stock modification, but we offer quality Choate folding stocks that have been customized in-house to fit our mounts.

Model# M6-Sa

  • Fits the new Inland Manufacturing carbines and Auto Ordnance carbines.
  • This is a slightly shorter version of our M6-B mount
  • Length of mount: 7.812″
  • Picatinny rail has 18 slots
  • Requires minor stock modification, but we offer quality Choate folding stocks that have been customized in-house to fit our mounts.

Please note that none of these will fit carbines made under the brands: Universal, Plainfield, Iver Johnson, National Ordnance or Alpine (unless they’ve been fitted with a GI profile barrel).

Also note that the M6-Sa replaces the older model M6-S. We are no longer manufacturing the M6-S (but are currently selling a batch of new-old stock because it fits Auto Ordnance carbines just as good as the M6-Sa does).


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.

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 needed for the most part (although some stocks do require minor inletting – removal of some wood or plastic – inside the forend, but the old G.I. stocks we’ve tested require no modification. See below for more information). 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 (which all take the M6-B mount), a new Auto Ordnance carbine, or the new Inland Manufacturing carbine (both of which take the M6-Sa). These models will likely perform better, and will be compatible with after-market parts, stocks and accessories.

A very small number of the early production commercial carbines from the late 1950s and early ’60s actually do have MIL SPEC barrels, as 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.


Regarding the minor stock modification needed for some models:

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 a small amount of 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 inherently compatible and will provide for a true, “drop-in” (no modification) installation.

Installation notice:

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:
