Comp M5 turret diameter is different from that of the T1 and T2. ATA, Comp M5 caps are incompatible with T1 and T2. ATA M5 is also not compatible with Aimpoint M5b which has its own elevation and windage caps. ATA for T1 and T2 can be found here: ATA (Adjustable Turret cap, Aimpoint Micro)
ATA, Comp M5 consists of 2 caps and 2 discs.
ATA, Comp M5 (Adjustable Turret cap, Aimpoint Comp M5) is a simple and robust solution. ATA, Comp M5 gives the user the ability to make adjustments to either the windage or elevation without removing the caps.
ATA, Comp M5consists 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, Comp M5.
ATA, Comp M5 caps are serrated to assist in its installation. There are 12 serrations total, matching the tick marks on the inside of the factory T1 cap.
The internal O ring prevents undue moisture from entering the ATA, Comp M5. In water immersion testing, ATA, Comp M5'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, Comp M5, please do not remove the O rings already present on the sight.
ATA, Comp M5 is billet machined in 17-4 stainless steel, and QPQ treated. ATA, Comp M5 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, Comp M5 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, Comp M5'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, Comp M5's 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, Comp M5 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). ATA caps ship with lubricated O rings installed.
ATA, Comp M5 is proudly made in USA. U.S. Patent No. 11,054,218
NOTE:
The adjustment caps on the ATA Comp M5 are NOT interchangeable with those on the T1/T2.
ATA is shipped with the internal O ring already installed. 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. In a pinch, petroleum jelly can be
used as a substitute, but we recommend using the correct lube (silicon
based O ring lube) for the ATA.
ATA caps should 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.
ATA disc's engravings are small, as the discs are small. For better visibility, white crayon or Laquer-stik (on Amazon) can be used to fill in the engraving.
ATA-TTE (tool-less turret, elevation) is an add on for ATA, Comp M5. If the TTE option is selected, the package will be shipped with both the standard caps, discs, and the TTE.
