NocPix BOLT P25R Thermal Imaging Scope with LRF

The P25R is the best place to start in the BOLT range if price is a major consideration and you primarily need a dedicated thermal scope for shorter and medium-distance use.

Although it uses the lowest-resolution detector in the BOLT family, you still get many of the important features found further up the range, including an integrated laser rangefinder, ballistic calculation, dual-battery system and conventional 30mm mounting.

If you want a noticeable increase in thermal detail and detection range, consider the BOLT L35R. For the strongest image quality and longest detection capability in the BOLT range, step up to the BOLT H50R.

The BOLT range is available in three main configurations. The biggest differences are thermal sensor resolution, lens size, detection range and magnification.

P25R: Best for customers prioritising price and predominantly shorter-distance use.

L35R: The middle-ground BOLT, with a worthwhile increase in sensor resolution and detection range over the P25R.

H50R: The premium BOLT, with the highest sensor resolution, longest detection range, better thermal sensitivity and widest magnification range.

All three include an integrated laser rangefinder, ballistic calculation and conventional 30mm scope-tube mounting.

The L35R's main advantages are its higher-resolution thermal sensor, larger objective lens and longer detection range.

The P25R uses a 256×192 sensor and 25mm F1.0 lens, while the L35R increases this to 384×288 and 35mm F1.0. Manufacturer-stated detection range increases from approximately 1,300m on the P25R to 1,800m on the L35R.

Both use 3.5–14× magnification and include integrated LRF and ballistic calculation. The P25R therefore makes sense when keeping the purchase price down is the priority, while the L35R is the worthwhile upgrade for customers wanting more thermal image detail and additional detection capability.

The H50R represents a substantial step up from the P25R. Sensor resolution increases from 256×192 to 640×512, while the objective lens increases from 25mm to 50mm.

The H50R also improves thermal sensitivity from ≤20mK to ≤18mK, increases refresh rate from 50Hz to 60Hz and provides a wider 3–24× magnification range.

The difference in manufacturer-stated detection range is also considerable: approximately 1,300m for the P25R compared with 2,600m for the H50R.

The P25R is primarily about value. The H50R is the better choice when image quality, longer-distance detection and retaining more useful detail under digital magnification justify the additional cost.

The P25R uses a 256×192 thermal detector with a 12μm pixel pitch. This is the lowest-resolution sensor in the current BOLT range and is one of the main reasons the P25R can be offered at a lower price than the L35R and H50R.

For customers mainly using the optic at shorter and medium distances, it provides an accessible route into a dedicated thermal scope. However, the higher-resolution L35R and especially the 640×512 H50R will provide greater thermal image detail and retain more useful information as digital magnification is increased.

NETD measures how effectively a thermal detector can distinguish small differences in temperature. In general, a lower NETD figure indicates greater thermal sensitivity.

The BOLT P25R is rated at ≤20mK. This helps the detector distinguish temperature differences within a scene, including when environmental conditions reduce thermal contrast.

The P25R combines a compact 25mm F1.0 objective lens with 3.5× base magnification. Its field of view is approximately 12.3 × 9.2 metres at 100 metres.

The smaller 25mm objective contributes to the P25R's shorter-distance positioning within the BOLT family. Moving to the L35R increases the objective to 35mm, while the H50R uses a substantially larger 50mm lens.

Despite being the entry model in the BOLT family, the P25R retains an integrated laser rangefinder with a manufacturer-stated maximum ranging distance of up to 1,200 metres under suitable conditions.

The scope also incorporates ballistic calculation functionality, meaning customers do not have to move to the L35R or H50R simply to gain the BOLT rangefinding and ballistic features.

NocPix gives the BOLT P25R a manufacturer-stated detection range of approximately 1,300 metres under its specified test conditions.

Detection range is not the same as identification range. Detecting that a heat source is present at a particular distance does not necessarily mean there is enough image detail to determine exactly what that heat source is.

Actual useful detail will vary with weather, temperature contrast, object size, terrain and the amount of digital magnification being used.

The BOLT platform combines an internal rechargeable battery with a replaceable 18650 battery. This provides the convenience of an integrated power source while allowing a spare 18650 battery to be carried and replaced when required.

NocPix states operating time of up to approximately 12 hours for the P25R under its specified test conditions. Actual runtime can vary with temperature, connectivity, recording and other settings.

BOLT provides an accessible route into the NocPix dedicated thermal riflescope range, with P25R, L35R and H50R models covering several sensor resolutions and price points.

ACE is the premium all-round range, offering higher-end imaging configurations, fast objective lenses and a choice of conventional 30mm or dedicated RM rail-mount models.

RICO2 places greater emphasis on longer-distance thermal observation, including larger objective options at the top of the range.

The P25R is therefore particularly attractive when you want the convenience of an integrated BOLT thermal riflescope with LRF and ballistic functionality while keeping the initial investment as low as possible.

NocPix's standard warranty policy provides a 3-year warranty on the main device, 2 years on the battery and 10 years on the thermal detector, subject to the manufacturer's warranty terms and eligibility.

Does the NocPix BOLT P25R have a laser rangefinder?
Yes. The P25R includes an integrated LRF with a manufacturer-stated ranging distance of up to 1,200 metres.

What sensor does the BOLT P25R use?
It uses a 256×192 thermal detector with a 12μm pixel pitch and ≤20mK NETD.

What is the detection range of the BOLT P25R?
NocPix states approximately 1,300 metres under its specified test conditions. Detection distance should not be confused with identification distance.

Is the L35R better than the P25R?
The L35R increases sensor resolution from 256×192 to 384×288, increases the objective from 25mm to 35mm and increases manufacturer-stated detection range from approximately 1,300m to 1,800m.

What is the difference between the P25R and H50R?
The H50R is the major upgrade, with a 640×512 sensor, 50mm objective, ≤18mK NETD, 60Hz refresh rate, 3–24× magnification and approximately 2,600m manufacturer-stated detection range.

What size scope mounts does the BOLT P25R need?
The BOLT P25R has a 30mm scope tube, so it requires suitable 30mm scope rings or a 30mm mount.

The NocPix BOLT P25R uses a conventional 30mm scope tube. This means it mounts using suitable 30mm scope rings or a 30mm scope mount.

When selecting a mount, the ring diameter must therefore be 30mm. You will also need to choose a mount suitable for the rail fitted to your rifle and ensure the selected height provides adequate clearance for the scope and objective.

The BOLT P25R, L35R and H50R share the traditional 30mm tube-style mounting format, so the same basic ring-diameter requirement applies across the current BOLT range.

If this product is included in Bamfords' free match mount offer, select a suitable 30mm mount for your rifle's rail type. If you are unsure which mount you require, contact Bamfords and we can help confirm compatibility before ordering.
