Forward Controls Design Adjustable Turret Cap For Aimpoint Micro

The Forward Controls Design Adjustable Turret Cap for Aimpoint Micro solves one of the most annoying problems with T1 and T2 red dots: fiddly, easy-to-lose adjustment caps. FCD set out to make zeroing faster and more convenient without removing caps every time you need to dial windage or elevation. The result is a purpose-built system that lets you make adjustments with the rim of a cartridge or a coin—no cap removal, no flipping, no fumbling. If you've spent the last few years losing tiny caps or cursing the multi-step adjustment dance on your T1/T2, this is a straightforward upgrade that actually makes the sight more user-friendly in the field.

The ATA system comprises two billet-machined 17-4 stainless steel caps and two rotating discs, each labeled clearly for elevation (UP) or windage (R) to eliminate confusion. The discs feature externally accessible slots that mate with the sight's internal adjustment indentations—simply rotate the disc with a cartridge, coin, or similar tool to dial your correction. The caps are serrated to match the 12 tick marks inside the factory Aimpoint cap, and each cap ships with an O-ring already installed. The internal O-ring design maintains the factory water-resistance standard, tested to 77 feet in immersion testing, matching the factory cap's performance. Since adjustments happen on the disc (not the cap), the caps remain stationary, and the whole system is faster than the conventional approach for shooters who need to iterate their zero.

Built and finished in the USA with 17-4 stainless steel and QPQ treatment, the ATA caps will hold up to hard use. Installation is straightforward—FCD ships them partially assembled so you can separate the cap and disc for easier installation, with instructions included. A small note: keep the O-rings lubricated with silicone-based lube (or petroleum jelly in a pinch) to maintain smooth operation, and if the caps start moving excessively during adjustment, a dab of O-ring lubricant will restore the right feel. This is a no-nonsense upgrade for anyone running an Aimpoint T1 or T2.

Frequently Asked Questions

Will this work on my Aimpoint M5?

No. The adjustment caps on the T1/T2 are not interchangeable with those on the M5. The ATA is designed specifically for T1 and T2 models.

Do I need to remove the existing O-rings on my sight before installing the ATA?

No. Do not remove the O-rings already present on the sight itself. Simply install the ATA caps and discs over them. The ATA has its own internal O-ring for additional sealing.

What tools do I need to adjust the turrets?

You can rotate the adjustment discs with the rim of a cartridge (.223, .308, .45 ACP, or 9mm), a coin, or any similar tool—no special tool required.

How does this maintain water resistance?

The ATA has an internal O-ring sealed inside each cap. Immersion testing confirms the system maintains water resistance to 77 feet, matching the performance of the factory Aimpoint cap. Keep the O-rings lubricated with silicone-based lubricant to maintain the seal.
