Series WXT, sight picture Black sight picture and scope of delivery adjustable revolver sight with Weaver base without separate front sight are the decisive purchase features.

This page does not describe a universal sighting system. LPA assigns each SKU to a specific firearm/milling or frame mount. Only when this mechanical counterpart matches do sight picture and micrometer adjustment become relevant.

What is this LPA sight?

What distinguishes the LPA-WXT series
adjustable S&W revolver sight with integrated Weaver base for an optional red dot sight. screw-mounted sight base for prepared frames with milled Weaver mount.
The integrated Weaver base can accommodate a compatible red dot sight without dismantling the mechanical sight. Optic, rings and their height are separate components.
One adjustment corrects the point of impact within its mechanical range. It does not compensate for a crookedly pressed-in rear sight, incorrect front sight height, or unsuitable firearm mount.

Sight picture Black sight picture
A black sight picture prioritizes clear contours of rear sight notch and front sight. It offers no additional luminous or fiber reference and depends especially on clean contrast between sight and target image.
Practical consequence: keep front sight and rear sight free of reflections and clean. With a dark target background, a bright target or adjusted lighting can help more than a changed sight adjustment.
The sight picture changes perception, not mechanical compatibility. WXT0407-F2 BLACK BAS remains tied to the series, firearm mount, and scope of delivery of this SKU.

Four decisions before ordering


Firearm and mount: The Weaver base creates the interface to the optic; red dot sight and suitable mount are not part of the sight.

Exact version: WXT0407-F2 BLACK BAS stands for series WXT with sight picture Black sight picture. A different end code can change scope of delivery or contrast picture.

Rear sight and front sight: No new front sight is delivered; the existing or separately procured front sight must geometrically fit the rear sight.

Mounting limit: The frame must have the confirmed drilling pattern and suitable threads; additionally, the exchange height of 10-10.5 mm must be maintained.

Only when these
When the four points match, the micrometer adjustment of LPA is a usable advantage. A reduced black match sight picture without luminous inserts is a matter of the chosen sight picture; mechanical fitting cannot be replaced by this. If you are undecided between two visually similar variants, you should first clarify the manufacturer code and mounting and only then decide between black, dots, white outline, fiber optic, or luminova.

Compatibility without abbreviation
LPA WXT0407-F2 BLACK BAS fits exclusively to the confirmed counterpart 629, 686, 586, 627, 66, 67, 696, 17, 19, 657, 610, 625, 29, 27 and newly for caliber .50. Manufacturer name and similar model number are not sufficient. Slide revision, year of manufacture, factory sight, optics-ready version, or already performed milling work can change the mounting.
The code WXT0407-F2 BLACK BAS is the most precise assignment on this page. When matching with packaging, LPA documents, or existing rear sight, use this code and not just the series designation WXT.
This SKU features an adjustable revolver sight with Weaver base without a separate front sight. A matching existing front sight is required for a complete sight picture.

Installation and mechanical fitting
The source describes a screw mounting on the prepared frame. The total height of the rear sight to be replaced must be 10-10.5 mm.
The source does not confirm universal mounting without adjustment. Before pressing in, professionally check the mounting, direction, and dimensions.
Take mounting direction and support surfaces from the firearm/LPA manual; do not guess based on the previous disassembly direction.
Do not install the sight with uncontrolled hammer blows. A suitable sight pusher or professional clamping and support tools distribute the force on the intended surfaces. Completely unload slide or frame and remove according to firearm manual before working on the sight mounting.
This SKU does not include a new front sight. Height and shape of the existing or separately chosen front sight must match the adjustment range of the rear sight.

Our assessment
LPA WXT0407-F2 BLACK BAS is useful for shooters who want a mechanically adjustable sight with a reduced black match sight picture without luminous inserts on exactly 629, 686, 586, 627, 66, 67, 696, 17, 19, 657, 610, 625, 29, 27 and newly for caliber .50.
Do not buy if reflex sight and matching rings/mount are not included; frame preparation and sight height must be correct. Also unsuitable if you need a highlighted fiber/luminova or dot reference in low light or if the existing mounting does not clearly match WXT0407-F2 BLACK BAS.

Black-Raptor short summary: Buy if: LPA code, firearm model/cut, scope of delivery, and desired sight picture fully match. Do not buy if: only manufacturer name or a similar-looking dovetail serve as proof of fit.

Product-specific practical tips

Practical tip: Read compatibility up to milling WXT0407-F2 BLACK BAS is intended for 629, 686, 586, 627, 66, 67, 696, 17, 19, 657, 610, 625, 29, 27 and newly for caliber .50. Model family, generation, slide/frame version, and rear sight cut must all match. A similar manufacturer designation is not enough.

Practical tip: Mounting base before click adjustment Check frame support, hole pattern, thread, and confirmed replacement height 10-10.5 mm before tightening. Secure and tighten screws only according to LPA/firearm manufacturer instructions. Only a mechanically centered and stable basic mounting makes the later click correction meaningful.

Practical tip: Treat front sight height as part of the system A front sight is not included. The existing or separately chosen front sight must fit the rear sight height and firearm platform; otherwise, the point of impact lies outside the usable adjustment range.

Practical tip: Black sight picture right
g keep front sight and rear sight reflex-free and clean. With a dark target background, a bright target or adjusted lighting can help more than a changed sight adjustment. Limit: This version is not the right choice if you need a highlighted fiber/Luminova or dot reference in low light.

Practical tip: Document changes After zeroing, note distance, ammunition, and click changes. With WXT0407-F2 BLACK BAS never change multiple adjustment directions at once if the cause of a deviation is not yet clear.

Controlled zeroing and adjustment
After mounting, first completely unload the firearm and check for a solid sight picture, free slide/cylinder movement, and safe function. Then work at an approved shooting range with suitable protective and safety equipment.
Start with a defined distance and the same ammunition. A clean group is more meaningful than a single hit. First determine the average point of impact, then correct height or windage in small documented steps. Use the rotation direction from the LPA manual.
Since WXT0407-F2 BLACK BAS only guides the rear sight, an incorrect existing front sight can use up the available elevation range. If the adjustment reaches its stop, do not turn further; first clarify mounting, front sight height, firearm fit, and ammunition.
After confirming zero, do not tighten adjustment screws "just to be safe." Control marks and documented click positions help detect later movement.

Scope of delivery and additionally required parts
Confirmed or assigned to the SKU: adjustable revolver sight with Weaver base without separate front sight; mounting screws, if named in the specific source description.
Not included: suitable existing front sight; firearm; ammunition; sight pusher or other mounting tools; reflex sight and Weaver-compatible optic mount, unless explicitly stated otherwise. Product images may show firearm or complete sight picture, although only the designated component is sold.

Comparison and suitable alternatives: WXT combines mechanical revolver sight and Weaver base. TXT omits the integrated optic rail and remains the slimmer pure sight solution. Within the same series, SKUs mainly differ by firearm fit, front sight scope, and sight picture.

Care and function check
Keep sight body, rear sight cutout, and adjustment screws free of sand, powder residue, and dried oil. Do not leave cleaning agents in fiber, Luminova, or click mechanism. After shock or visible movement, confirm zero again.
Monitor mounting screws and frame contact via control marks. Move adjustment screws only within the intended range; a stop is not an invitation to use more force.
