Shown at right on a C39 pistol, the forward, low mounting enabled by the UltiMAK system provides a better, more sensible optic sight height, without adding weight or bulk to the gun. Our C39 pistol requires the shims. whereas the V2 model we tried did not. The M17 optic mount allows co witnessing of the iron sights with most tubular reflex type sights, such as Aimpoint. The railed, synthetic lower handguard shown will require slight modification (See Below)*.

Here is the M17 on the C39V2 pistol. This installation did not require shims, and Magpul lower handguard made the process very easy. With QD sling sockets all around, front and back and the mini AFG, this is a versatile setup. All it needs is a quality optic sight, mounted low for co witnessing and you're good to go.

Here you see the M17 mounted on the RAS-47 pistol with the Aimpoint Micro H1 Standard. The Magpul handguard shown is fully UltiMAK compatible, allowing a simple, drop-in installation with no shims. Notice how the UltiMAK M17 optic mount is integrated seamlessly into the gun's profile. M17 on RAS-47 with Magpul handguard
*The plastic (synthetic) handguard at right will need to be cut down slightly as shown. We started with a bench grinder and then finished it off with a file. The object is to remove interference with the M17 optic mount by taking off a small portion at the middle of the top of the handguard (see red line). When finished, the M17 optic mount should not contact the handguard. Quite simple; it only took a few minutes. Plastic, railed handguard modification for UltiMAK M17
**Our C39 pistol (shown above) has the smaller barrel of ~0.6" diameter at the optic mount clamping position inside the lower handguard. That small diameter is usually only found on a certain few AKs chambered in the 5.45 and 5.56 mm calibers. A ~0.6" barrel requires our shim set SH-1. It is therefore a good idea to measure your barrel diameter about one to two inches in front of the rear sight block. The lower handguard will need to be removed to take the measurement. An approximate barrel diameter of 0.6" (about 0.595" to 0.610") requires the shims. A barrel of approcimately 0.7" does NOT need shims. Our RAS-47 pistol does NOT need shims, NOR did the C39V2 we tried. Shown at right on a Romanian AKM, you see the shims in place. This photo also depicts the position of the barrel clamps relative to the rear sight block on these AK pistols.
