Description
Laylax Prometheus EG Barrel for G&G CM16SRS (6.03mm – 205mm)
Here is a LayLax Prometheus EG inner barrel for the G&G CM16 SRS, with a 6.03mm tight bore and a length of 205mm. The CM16 SRS is a short-barrelled member of G&G’s CM16 family, and this barrel is cut to suit it, giving the rifle a precise bore without changing its outside dimensions.
Prometheus is the internals brand of LayLax, and its EG barrels are made in many lengths, each listed against particular replicas.
Material and tolerance
The EG series is made from stainless steel and listed with a bore tolerance of plus or minus 0.01mm. A hard, corrosion-resistant barrel is less likely to pick up dents or pitting.
At 6.03mm the bore is a tight one. A narrower gap around the BB means less air escapes past it, which tends to improve consistency. It also means the barrel rewards clean, good quality BBs and a well-set hop-up.
Fitting
To fit it, strip the replica far enough to remove the hop-up unit and original barrel. Fit the bucking to the new barrel with the window aligned, slide it into the hop-up chamber and reassemble. Set the hop in small steps and have the replica chronographed before you play, because a tight bore barrel can change muzzle velocity.
Why upgrade the barrel
G&G’s CM16 range is a common first AEG, and once the rifle has seen a few seasons the barrel is a sensible thing to upgrade. Factory barrels are made to a price and can vary in finish. Replacing it with an EG barrel, and fitting a fresh bucking at the same time, gives you a better base for consistent shooting at the short to medium ranges a compact rifle is used at.

Compatibility
This barrel is listed for the G&G CM16 SRS. Barrel lengths and hop-up units differ between makers and even between versions of the same model, so please measure your existing inner barrel or check your replica’s specification, or contact us, before ordering. A retailer lists the 120mm G&G version as suiting outer barrels with an 8.6mm to 9.2mm inner diameter.
The hop-up rubber is not listed as included, so plan to reuse your current bucking or fit a new one at the same time.
Care and maintenance
Push a clean patch through the bore with a rod regularly, working from the hop-up end where you can, and keep the barrel dry inside. Stick to clean, seamless BBs, avoid dropped or dirty ones, and never oil the hop-up rubber.
Who is it for?
It is for CM16 SRS owners who want a straightforward, reliable barrel upgrade, whether they are tuning a new rifle or refreshing one that has seen a lot of use.
Please note: The hop-up rubber is not listed as included. Have your replica chronographed after fitting a new barrel.
