Description
Laylax Prometheus EG Barrel for AK74U (6.03mm – 260mm)
This is a LayLax Prometheus EG inner barrel listed for AK74U models, 260mm long with a 6.03mm tight bore. The AK74U is the short, folding-stock member of the AK family, and this barrel gives it a precise stainless steel bore in place of the factory part.
LayLax sells its upgrade internals under the Prometheus name, with EG barrels offered in lengths to suit a long list of replicas.
Construction
Like the rest of the EG range, this barrel is stainless steel, with a bore tolerance listed at plus or minus 0.01mm. Stainless steel is stiff and resists corrosion, so this is a long-term part.
Its 6.03mm bore is tighter than many stock barrels. With less room around the BB, less air is wasted and the BB has a more even path to the muzzle, which helps groups stay tight once the hop is set correctly.
Fitting
Installation means taking out the hop-up unit and factory barrel, transferring or replacing the hop-up rubber, and fitting the EG barrel with its window lined up. Put everything back together, adjust the hop a little at a time and check the power on a chronograph before a game day.
The AK74U on the field
The AK74U is a handy, characterful replica for CQB and woodland. AK-type replicas can be a little more involved to strip than an M4, so read up on your model first. Once the barrel and a fresh bucking are fitted, set the hop with the BB weight you intend to use and the rifle will have a better base for consistent shooting.

Compatibility
This barrel is listed for AK74U models. 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.
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
Keep the bore clean with a rod and patch after every few outings, finishing dry. Clean, seamless BBs of one consistent weight protect both the barrel and the bucking. If a BB ever lodges in the barrel, clear it gently with a cleaning rod rather than firing more BBs behind it.
Who is it for?
It is for AK74U owners who want a quality barrel upgrade or a durable replacement for a worn barrel.
Please note: The hop-up rubber is not listed as included. Have your replica chronographed after fitting a new barrel.
