- description
This replaces the slide assembly with a fixed chassis. Only the bolt inside cycles, so the top rail and everything on it sit still through a string of shots. The practical effect is that a red dot stays where you put it instead of bouncing and resettling between rounds.
Taking the reciprocating mass down to a bolt also speeds the cycle up and takes the wrist fatigue out of a long game. At 185 g the front end is lighter than a full alloy slide, and the skeleton windows leave the inner barrel visible.
Hop-up adjustment moved up to the top rail as a TDC mechanism, so pressure comes down evenly without anything being pulled apart. CTM quote it for heavier BBs, 0.28 g through 0.40 g.

Good to know before you buy
This is a 5.1 conversion. A 4.3 will not take it, so check which Hi-Capa you own.
Your existing slide-mounted optic plate becomes redundant. The rail is part of the chassis now, which is the whole idea, but it means the old mount is scrap.
A fixed barrel and a light bolt change the gas behaviour. Expect to re-chrono and to spend an afternoon on the hop before it shoots the way you want.
Heavier BBs are what this is tuned around. If you shoot 0.20 g it will work, but you are leaving most of the benefit on the table.
Three of the six finishes are cheaper than the other three as things stand, so the colour choice moves the price here.
Frequently asked questions
Will it fit a 4.3?
No. The conversion is listed against the 5.1 only.
Why does the optic stay still?
Because the chassis and the rail do not reciprocate. Only the bolt inside moves, so nothing bolted to the top travels with it.
Do I keep my own barrel?
The inner barrel stays and is visible through the skeleton windows. The outer chassis is what replaces the slide.
How do I adjust the hop?
From the top, with the integrated TDC mechanism. No stripping needed.
What BB weight should I run?
CTM cite 0.28 g to 0.40 g, which is where a fixed barrel and even hop pressure pay off.
How much does the kit weigh?
185 g.
