Vector Optics X-ACCU 25.4mm Dovetail Adjustable Scope Mounts (XASR-2515)

More adjustment. More range. More flexibility.

The X-ACCU Adjustable Match Mounts are designed for shooters who have reached the limits of their scope's internal elevation adjustment. By allowing the scope to be pitched forwards or backwards, these mounts let you reclaim valuable adjustment travel for either extreme long-range shooting or very close-range zeroing.

 

Pitching the scope down preserves more upward elevation adjustment, making it ideal for long-range shooting where significant holdover or turret adjustment is required. Conversely, pitching the scope upwards can be useful when compensating for rifles fitted with built-in MOA rails or for shooters wanting to optimise a setup for shorter distances.

 

Manufactured by X-ACCU, the premium mounting division of Vector Optics, these match-grade mounts are machined from 6061-T6 aluminium alloy to a higher standard than the entry-level VictOptics range. They provide excellent alignment, repeatability and rigidity, making them ideal for PCP air rifles, airsoft rifles and other low or zero-recoil platforms.

 

For best performance, we strongly recommend installing these mounts using a calibrated torque screwdriver capable of 2-5Nm. Correct torque helps maintain zero, prevents movement during use and avoids damage caused by overtightening.

  • Disclaimer for Dovetail Scope Mounts: Compatibility Alert

     

    Dovetail mounts are crafted to offer broad compatibility with most dovetail rails. However, it's essential to note exceptions in rail dimensions used by specific gun manufacturers.

     

    Manufacturers like BSA and GAMO employ a 13mm dovetail rail (measured at 13.5mm), while FX and Walther utilize a 9.5mm dovetail rail. These dimensions differ from the standard 11mm dovetail scope mounts.

     

    Fitting standard dovetail mounts onto oversized dovetail rails may lead to incorrect gun/mount/scope alignment. On the other hand, fitting them onto undersized rails could result in sliding or rocking when installed.

     

    For firearms featuring these over/under-sized dovetail rails, Vector Air recommends either utilizing equal pull mounts like BKL or considering the conversion to the modern and standardized Picatinny RIS (Rail Integration System). Ensuring proper compatibility guarantees an optimal shooting experience.

  •   Disclaimer: Proper Use of Scope Mounts on Recoiling Guns

     

    Before using scope mounts on recoiling guns, such as spring/gas ram air rifles, rim/centerfire guns, and blowback airguns, please read and understand the following disclaimer:

     

    Creep Risk: The use of dovetail mounts on recoiling guns may result in creep due to the absence of anti-recoil locking pins. Creep is the gradual movement of the mounts along the gun's rail during recoil.

     

    Recommendation: It is strongly recommended to use recoil arrester blocks or recoil stoppers to mitigate the risk of mount creep. The Vector Optics Riflescope Recoil Stopper (SCOT-05) is one such product that can help stabilize your scope mounts.

     

    Alternative Solution: An alternative solution to prevent mount creep is to convert your dovetail rails to Picatinny rails. Picatinny rails offer a more secure attachment and eliminate the need for recoil pins and arrester blocks.

     

    Adapter Rails: You can find dovetail-to-Picatinny rail conversion adapters, such as the  Eagle Vision Dovetail to Picatinny RIS Conversion Rails. These adapters provide a stable platform for your scope mounts, reducing the risk of movement during recoil.

     

    User Responsibility: It is the user's responsibility to ensure that the chosen mounting solution is appropriate for the specific firearm and shooting application. Improper use may lead to damage to equipment, decreased accuracy, or potential safety hazards.

     

    Consultation: If you have any doubts or concerns regarding the compatibility of your chosen scope mounts with your firearm, consult with a qualified gunsmith or a knowledgeable professional in the field.

     

    Disclaimer Acceptance: By using dovetail mounts on recoiling guns, the user acknowledges the potential risks and accepts full responsibility for the choice of mounting solution and any consequences that may arise from its use.

     

    Remember, safety should always be a top priority when using firearms and related accessories.

    Vector Optics X-ACCU 25.4mm Dovetail Adjustable Scope Mounts

    After placing the order online I received Dove tail adjustable mounts within 3 day so I would say fast delivery as it had to come to Northern Ireland. The Vector Optics X-ACCU 25.4mm Dovetail Adjustable Scope Mounts (XASR-2515) are high quality great value and fitted perfect. After mounting and levelling my scope it was easy to adjust the MOA of my Daystate Redwolf now shoot out to 100 yards accurately. I would high recommend Vector Air for all your shooting needs.

    Hi Alex, couldn’t have said it better ourselves! These mounts are spot on for no-recoil guns like PCP air rifles, perfect for squeezing that extra range out—ideal for sub-16 joule builds. And Northern Ireland delivery? We feel you—getting stuff across with Royal Mail and Parcelforce these days is a proper headache, so we’re chuffed it arrived safe and sound!
