Airtech MAXX TDC Trolley ER-Hop & M-nub (6mm Length)
£15.00
The Carbon Airtech MAXX TDC Trolley ER-Hop & M-nub (6mm Length) is a precision hop-up upgrade for MAXX M4 and SCAR chambers, built to apply even top-down pressure across longer ER-Hop patches. It is designed for players chasing tighter shot-to-shot consistency, improved air seal and more stable backspin in DMR and long-range builds.
The Carbon Airtech MAXX TDC Trolley ER-Hop & M-nub (6mm Length) is a purpose-built upgrade for MAXX hop-up chambers, designed to get the most from ER-Hop and R-Hop style setups. Its extended 6mm contact surface works across longer hop windows to apply a centred, even load through the bucking onto the patch, helping reduce uneven pressure and unwanted tilt.
In practical use, that means more consistent hop application and a more uniform spin on the BB, which is exactly what matters in rifles built for accuracy at range. For DMR and precision-focused AEG builds, this can help deliver steadier flight paths and more repeatable performance from shot to shot, especially when used with compatible flat-hop or MR-Hop style buckings.
This version uses a modified trolley shape for a tighter fit in the chamber, along with a radiused M-nub profile that matches the MAXX hop window more cleanly. The polycarbonate construction keeps it durable without adding unnecessary complexity, while the adhesive-backed M-nub helps maintain proper contact during installation and use.
It is compatible with MAXX ME, MI and selected SCAR SV series hop-up chambers, including PRO, SPORT and certain branded variants. Please note this is the trolley and M-nub upgrade only; the MAXX hop-up chamber itself is not included. For best results, it makes sense alongside quality hop rubbers and precision inner barrels. Add it to your build when you want your MAXX chamber working properly with a 6mm ER-Hop patch.
