Finally, there’s a well-designed detachable and adjustable precision sighting system, with plenty of options to fit your needs, for the A4-type flat-top M15 using the JP gas block or rail-type sight block. If you have a flat-top gun with a fixed front sight, our front sight/gas system combination will give you a way to have both front and rear detachable sights. You may also choose to use our front sight mounting block to achieve maximum sight radius.

JP15 with Mangonel flip up front and rear QD sights supplementing Holosight: JP15 with JPFS-ALS adjustable front sight and A-2 adjustable shorty rear.

The JPFS-ALS is not a plain old military version but a Lyman #93 target globe with inserts for maximum flexibility and precision. This new design features .300" of possible height adjustment to allow use with a wide variety of rail heights and rear sight hardware. It has a slide-lock adjustment method with an additional set screw lock under the sight platform for added rigidity and easy adjustment. When used with an A2-type rear sight such as the DPMS shorty A2 sight, it allows the rear sight zero to be set to actual zero for proper use of the elevation dial. When used with receiver sights that have more elevation travel, our adjustable front sight allows for a lower overall sight plane relative to the bore, resulting in a tighter cheek weld on the stock if desired.
The JPSRTS is the solution for supplementing a long-range optic or precision iron sight setup where fast, reflexive short-range engagement from point-blank to 35 or 40 yards is a necessity. We have re-designed the SRTS making just a bit higher and also night sight compatible. Our local police department started using the JPSRTS as their back up system on M-4 type carbines with EOTec main optics. They found that if they had to stand outside a building in the extreme cold waiting to make an entry, the optic would fog up immediately upon entering a heated, humid building rendering it useless. They needed a non-cowitnessed system that was available without having to remove the main optic. The SRTS was perfect for this application. The JPSRTS is adjustable for point of impact and is quick detachable on the JP tactical rail accessory. Supplied with five colored front sight inserts. It is now the same sight plane as a standard A-2 sight system, allowing the operator to roll into it without changing his cheek weld. It will take a standard Novac rear sight with tritium lighting and any standard A-2 front sight if night sights are needed.

Riser block to add 1/2 " of height for any rail accessory where needed, such as JPSRTS or any standard QD type scope rings that are too low for flat-top mounting. Two blocks in use in the above photo.

If a more rugged rear sight is needed, the DPMS detachable flat-top sight is the choice. Essentially an A-2 rear sight without the handle, this compact sight will attach on any Weaver or Picatinny rail and has the standard twin apertures for fine or course sight picture.
