Description
Xcortech XT501-MK2 Tracer Unit (14mm CCW & Up to 1200RPM – Black)
The Xcortech XT501-MK2 is a black tracer unit with a 14mm counter-clockwise thread, designed to light up tracer BBs on replicas firing at up to 1200 rounds per minute. It fits on the muzzle like a mock suppressor and lets you see every shot in low light.
Xcortech is known for airsoft electronics such as chronographs, tracers and mosfets. The MK2 is the newer version of the XT501 and, according to a retailer listing, uses more powerful UV LEDs, a motion sensor that saves power automatically and a low battery indicator. It is a strong choice for players with fast-firing AEGs who want a tracer that keeps up.
How a tracer unit works
A tracer unit sits on the muzzle like a mock suppressor. As each BB passes through, a burst of light, usually ultraviolet, charges the glow-in-the-dark coating on a tracer BB, so it leaves a bright streak along its flight path. You can follow every shot, see exactly where your BBs are going and walk your fire onto a target, which is a real advantage in night games, dark buildings and low-light woodland.
Tracer units only work with tracer (luminous) BBs. Ordinary white or black BBs pass through without glowing, so stock up on tracer BBs of a weight that suits your replica and hop-up.
XT501-MK2 features
As named, the unit handles rates of fire up to 1200RPM, so it suits high-speed AEGs as well as standard builds. A retailer listing gives the length as 156mm and the weight as 140g without batteries, describes a metal body and a simple on/off switch, and says the built-in 3D motion sensor powers the unit down to save batteries when it is not being moved. A low battery indicator warns you before it stops working.
The same listing states that it runs on four AAA batteries, which are not included.

Compatibility
Fits replicas with a 14mm counter-clockwise (CCW) muzzle thread, the most common thread on AEGs; replicas with clockwise or other threads need a suitable adapter. Make sure the inner barrel does not protrude into the unit. Requires tracer BBs.
Care and maintenance
Remove the batteries, or charge and switch off the unit, before storing it, and keep it somewhere dry. Wipe the outside clean after games and check that no BB fragments or dirt are lodged in the bore, as debris in the path of the BB can affect accuracy. Never look into the light source while the unit is switched on.
Before each game, check the unit is screwed on fully and straight and that the inner bore lines up with your barrel. A unit that is not aligned can clip BBs, causing poor accuracy and wear. Clean your inner barrel regularly and use good-quality tracer BBs, as dirty or damaged BBs leave residue in the unit.
Who is it for?
Players with fast-firing AEGs who take part in night games or play at dark indoor sites, and anyone who wants to see their shots to fine-tune hop-up.
Please note: Batteries (4 x AAA, per a retailer listing) and tracer BBs are not included. Always wear eye protection.
