SSX23/SSX303 Mini TDC Thumbscrew

Mini TDC screw for hop-up adjustment on gas pistol SSX23 and SSX303 carbine by Tridos Design.

Compatible with Novritsch and Hadron Design TDC covers with M4 threads. The screw, made of anodized aluminum, features a low profile and laser-etched markings for hop-up adjustment direction.

Initial installation may be tight – we recommend screwing it in and out a few times.

Mini TDC adjustment screw for hop-up on SSX23/SSX303 weapons from Tridos Design replaces the original screw on your TDC cover and is fully compatible with:

• Novritsch TDC cover for SSX23 and SSX303
• Hadron Design’s TDC cover for MK23
• Most other TDC covers with M4 threads

Made with a slightly wider M4 thread to prevent self-loosening after installation. Additionally, a dab of thread glue is applied for even more stable fixation. The screw is crafted from anodized aluminum 6061, featuring a laser-etched hop-up adjustment indicator. Its knurled sides allow for easy hop-up adjustment, even with gloves. The low profile ensures it won’t interfere with aiming or holster use. It’s an ideal upgrade for SSX303.

Caution:
During the initial installation, the screw may be a bit tight – we recommend screwing it in and out a few times to make it easier to turn.
