Frequently Asked Questions

Need To know more?

Will NexxSpeed Parts Fit My Hi-Capa Clone?

NexxSpeed Hi-Capa parts are designed for the Tokyo Marui Hi-Capa. Many clones follow a similar design, but tolerances vary between manufacturers, so some parts may need fitting. Check each listing and contact us if you're unsure.

What's the Difference Between the NexxSpeed TDC and TDC V2?

Both are CNC-machined aluminium TDC hop units for the Tokyo Marui Hi-Capa. The V2 is NexxSpeed's newer design. Check the product listings for the full feature set of each version.

What Does a Short-Stroke Buffer Do?

A short-stroke buffer reduces how far the slide travels as it cycles. This can make cycling faster and more gas-efficient, and it also helps cushion internal parts. Check compatibility with your pistol before fitting.

NexxSpeed Pistol Upgrades

NexxSpeed produces CNC-machined upgrade parts, mainly for gas blowback pistols. Many components are machined from aluminium, including 7075 aluminium, to improve stability, durability and overall performance, and many are available in a choice of colours so you can personalise your build.

Tokyo Marui Hi-Capa

NexxSpeed's TDC hop units, including the newer V2, are machined from aluminium for a precise seal around the nozzle and let you adjust hop-up without stripping your pistol. CNC blowback units, hammers, slide catches, recoil guide plugs, hammer protection pads and short-stroke buffers help your Hi-Capa cycle smoothly and stand up to hard use. The 120% enhanced recoil springs are made from stainless steel and fit Tokyo Marui Hi-Capa 4.3, 5.1, Gold Match and 1911 models.

Action Army AAP-01/C

For the AAP-01 and AAP-01C, NexxSpeed offers a CNC aluminium hop-up chamber and an adjustable CNC aluminium trigger. See more in our AAP-01 parts and Action Army range.

M4 AEG

NexxSpeed's CNC aluminium hop-up chamber for M4 AEGs uses a hop arm built from layered steel sheets to provide the right elasticity on the nub for consistent hop pressure.
