Forward Controls Design ATA (Adjustable Turret cap, Aimpoint Micro)

Description

ATA (Adjustable Turret cap, Aimpoint Micro and Comp M5)  is a simple and robust solution.  ATA gives the user the ability to make adjustments to either the windage or elevation without removing 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 make adjustments to 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't be taken to Aimpoint specified depths without the caps on, 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).  Also included are two extra ATA internal O rings (ATA caps ship with lubricated O rings installed).
