Most High Power shooters like beef, the kind that offers rigidity and durability to our Service Rifle scopes, as well as the confidence that neither scope nor mount nor rings are going to move under recoil or during handling. Choices in beefy, made-in-the-USA cantilever mounts for big 34 mm scope tubes don’t exactly abound, but the number just increased by one with the UTG Pro P.O.I. Service Rifle mount.
Leapers tailored its UTG Pro P.O.I. Service Rifle Mount to attach its new Integrix iXF 4.5x28 Service Rifle scope’s 34 mm scope tube to the Service Rifle’s Picatinny rail. This cantilever mount has 3.7 inches of offset to complement the Integrix scope’s 3.7 inches of eye relief. Even if you’re a shooter who places nose against charging handle, the UTG Pro P.O.I. mount will likely provide proper eye relief with your own chosen Service Rifle scope, as well, but of course your own scope’s eye relief and tube length, and your individual sighting technique will determine that. The gap between the P.O.I mount’s rings measures 2⅜ inches, more than enough for any scope’s turret assembly, with leeway for sliding the scope fore and aft in the rings for more eye relief adjustment.
Solid Locking Bars
Made of hard coat anodized 7075-T6 aluminum rated for .50 BMG recoil, the P.O.I. mount differs from other typical mounts in that its locking bars do not also serve as clamp screws; instead, the P.O.I. has three locking bars machined integral to the base that engage the Pic rail slots, and two clamping locking plates, each with dual spring-loaded guide rods and a single screw. This beefy feature takes all the slop, wriggle and rattle out of the P.O.I.’s rail clamps that we deal with on lesser mounts. Does it really make a difference downrange? Perhaps not, but such attention given to engineering detail and quality construction can’t help but boost confidence in our equipment.
Pic rail slots on my Service Rifle’s White Oak upper receiver measure a consistent .402 to .406 inch wide. The three locking bars on the UTG Pro P.O.I. mount measure .390 to .398 inch wide, providing excellent fit while allowing for a few thousandths dimensional differences in Pic rails. When installing mounts or rings on Pic rails, remember to apply forward finger pressure while tightening clamping screws because the rifle, in effect, recoils backward against the locking bars, and pushing forward on the mount during assembly presses the locking bars firmly against the back edge of the slots so that the locking bars, rather than simply the mount clamps applying transverse pressure, lock the mount in place under recoil.
High Torque Values
Another nod to design well done, the P.O.I.’s locking plate screws and ring screws are all Torx T-25 size. UTG includes an angled T-25 Torx wrench with the mount, but don’t use it to tighten down screws the last bit—use a torque wrench.
An added nicety is that UTG printed the maximum recommended torque values for ring and mount screws right on the packaging, but if you already tossed that out or later move the mount to a different rifle, they’re also stamped on the underside of the mount. In my experience, most gun owners don’t use a torque wrench when tightening these screws, and many go way overboard in driving screws gorilla-tight in ordinary rings and bases. If it doesn’t strip screws or screw heads on assembly, it may do so when removing a scope, which can cost $25 to $40 (or more) per hole to drill out stripped screws and rethread or chase the holes.
Note that UTG’s recommended 25 inch-pounds for ring screws and 35 inch-pounds for mount screws are maximums for its own P.O.I. mount rated for the recoil of the .50 BMG cartridge. Our 5.56 mm NATO/.223 Rem. Service Rifles have little recoil, and so UTG’s maximums aren’t really necessary for our purpose. Most manufacturers recommend maximum torque of around 17 inch-pounds for ring screws and 25 inch-pounds for base/mount screws, even for some magnum cartridge rifles. But if you want to torque those P.O.I. screws to the maximum recommended limit, this mount’s got the beef.
The UTG Pro P.O.I. Service Rifle Mount is just now being released at this writing (January 2026) and should be on dealer shelves in early 2026, with an MSRP of $219.97. For more information and to reserve a mount for yourself, visit the Leapers website.
