Uncovering the JP Enterprises 34mm Eye Relief Scope Mount, Picatinny Rail: Real Review
When precision is paramount and every shot counts, the supporting cast of your optical system is just as critical as the optic itself. I’ve spent over a decade wrangling gear through workshops, labs, and out in the unforgiving embrace of the elements, and I’ve learned that even the most sophisticated optics are only as good as their connection to the platform. This quest for rock-solid reliability led me to the JP Enterprises 34mm Eye Relief Scope Mount, Picatinny Rail. My previous scope mount, a well-regarded Vortex, was out of stock during a critical build phase, forcing me to explore alternatives.
What initially caught my eye about this JP Enterprises offering was its reputation for robust construction, a hallmark of the brand. The product description highlighted an integrated recoil lug and a 20 MOA cant, features that immediately spoke to the needs of a shooter pushing the limits of their equipment. My own need was straightforward: a stable, repeatable mount for a high-magnification scope on a precision rifle platform that could handle the stresses of repeated recoil without shifting.
Upon unboxing, the immediate impression was one of serious engineering. The machining felt exceptionally precise, and the anodized finish offered a satisfyingly matte, non-reflective surface. While I considered a few other brands known for their Picatinny mounts, the integrated recoil lug and the specific 20 MOA inclination of this JP mount set it apart, offering a potential edge for long-range engagements. My initial reaction was a quiet confidence, a feeling that this mount was built to do exactly what it promised.
Real-World Testing: Putting JP Enterprises 34mm Eye Relief Scope Mount, Picatinny Rail to the Test
First Use Experience
My testing grounds for this JP Enterprises mount were primarily the rifle range, with extended sessions focused on accuracy drills and load development. The initial setup required a Torx wrench that, thankfully, was included with the mount, simplifying the installation process. The mounting straps secured firmly to the Picatinny rail with five countersunk screws, and the scope rings themselves, six screws per side, tightened down with a reassuring evenness.
Despite its robust construction, the mount proved surprisingly straightforward to use. Once the scope was properly seated and torqued, a quick bore-sight confirmed its alignment. The intermediate height of the mount comfortably cleared the 56mm objective bell of my Sightron scope, even with a scope cover in place, a crucial detail for practical field use.
During that initial range day, the most notable observation was the sheer stability. The scope stayed precisely where I dialed it, with no perceptible shift or movement even after a full afternoon of firing. This was a stark contrast to some mounts I’ve used in the past that required frequent re-zeroing after just a few rounds.
Extended Use & Reliability
Over several months and numerous range days, the JP Enterprises 34mm Eye Relief Scope Mount, Picatinny Rail has proven itself to be an incredibly reliable piece of equipment. It has been subjected to the jarring recoil of several different calibers, from .223 Rem to .308 Win, and it has held its zero without fail. Even after a minor tumble where the rifle slid a short distance on a gravel surface, the mount showed no signs of damage or misalignment.
The durability of the black anodized finish has been impressive, showing only minor cosmetic scuffs in high-contact areas, a testament to its hard-wearing nature. Cleaning and maintenance are minimal; a quick wipe down with a dry cloth and occasional check of the mounting screws is all that’s required. Compared to the budget-friendly options I’ve used in the past, this JP Enterprises mount is in a different league when it comes to long-term reliability.
The user feedback I’d read prior to purchase mentioned the recoil lug being “half a lug.” While I initially had similar thoughts, its performance has assuaged any doubts; it provides sufficient bedding against the rail to prevent any longitudinal movement. The ability to accommodate a 60mm objective bell, as confirmed by one user’s experience, speaks to the thoughtful design that balances height with clearance.
