Forward Controls Design Adjustable Turret Caps For Aimpoint Micros And Aimpoint Comp M5 - Black
The pair of Forward Controls Design ATA Caps replace the original elevation and windage adjustment caps that are difficult to use and easily lost, allowing you to adjust the optic without removing and/or losing the caps. If you have used an Aimpoint T1/H1/T2 or Comp M5, you have probably experienced the frustration of losing the original elevation and windage adjustment caps. Forward Controls Design solved that frustration with their set of Adjustable Turret Caps For Aimpoint Micros And Aimpoint Comp M5.
On an unmodified T1/H1/T2, to adjust either the elevation or windage, the user unscrews the cap, flips it 180 degrees, mates the two dots/protrusions with the two indentations on the sight adjustment, and rotates the cap, which in turn rotates the adjustment dial. As often is the case, adjustment is not done in a single step. The user makes the estimated adjustment, fires to verify the zero, and repeats if necessary. The caps are small and get lost easily. Such is the diminutive size of the caps it is not easy to dummy wire them. In any case, the sight itself is small and lacks much usable space for the tethering wire to loop onto.
The set of Forward Controls Design ATA Caps are a simple, economical, and robust solution. ATA gives the user the ability to make adjustments to either the windage or elevation without removing (and potentially losing) the caps. ATA consists of a pair of 17-4 SS billet machined cap with internal O ring, and a 17-4 SS rotating disc with an externally accessible top slot. The disc has two dots/protrusions that mate perfectly with the two indentations of the adjustment dial on the sight. To adjust either the windage or elevation, the user uses the rim of a cartridge (.223, .308, .45 ACP, and 9mm were tested) or a coin to rotate the externally accessible disc of the ATA.
The internal O ring prevents undue moisture from entering the ATA. In water immersion testing, ATA's ability to keep out water is on par with the single piece factory cap, to the depth of 77ft. To wit, T1 and T2 windage and elevation adjustments are water resistant even without the caps, they can not be taken to Aimpoint specified depths without the OEM caps on as Aimpoint only warranties the sights to the advertised depths with the caps installed. When installing the ATA, please do not remove the O rings already present on the sight.
ATA is billet machined in 17-4 stainless steel, and QPQ treated. ATA is shipped partially assembled (O ring is installed inside the cap, the disc is not installed inside the cap). It is far faster and easier to install the ATA on the sight with the cap and disc separated (instructions are provided on the back of the card).
In place of the factory marking UP/R with a counter clockwise arrow, ATA's discs have the counter clockwise arrow, but individual caps for UP and R. As much as it may seem common sense that the elevation adjustment is always on top, and the windage adjustment is always on the side, the marking UP/R can be confusing to new shooters. At the risk of being redundant, the ATA disc with the UP engraving is installed on top (for elevation), the disc with R engraving is installed on the right side (for windage).
ATA is shipped as a pair of caps and discs (one with UP and a counter clockwise pointing arrow engraved, and another with R and a counter clock wise pointing arrow engraved). QPQ black caps can be paired with either polished or the more discreet bead blasted stainless steel discs for improved contrast with the black caps. Also included are two extra ATA internal O rings (ATA caps ship with lubricated O rings installed). Additional spare pair of lubricated O rings are included.
Note: ATA are shipped with lubricated O rings installed inside the cap. It is a good idea to keep the O rings (both the O rings on the base of the adjustments, and ATA's internal O rings) lubricated with silicon based lubrication. ATA caps remain stationary when the discs are rotated, though it is acceptable for the ATA caps to rotate 90 degrees in either direction as long as the caps still apply pressure on the O ring on the base of the adjustment. When there is excessive cap movement (i.e. the caps easily moves in unison with the disc while making adjustment), silicon based O ring lubricant should be applied to ATA's internal O ring. In a pinch, petroleum jelly can be used as a substitute, but Forward Controls Design recommends using the correct lube (silicon based O ring lube) for the ATA. Optic, optic mount and battery cap are not included.
