Description
Laylax Prometheus EG Barrel for PTS Masada (6.03mm – 318mm)
This Laylax Prometheus EG barrel is a 6.03mm tight bore precision inner barrel, 318mm long, made to suit the PTS Masada. It is a straightforward upgrade from a standard inner barrel, designed to give more consistent shots and improved accuracy.
The EG series is Laylax Prometheus’s line of stainless steel precision barrels. Laylax bases the series on Tokyo Marui specification barrels and offers it in a wide range of lengths, so you can pick the exact length your replica needs. This one is made at 318mm to suit the PTS Masada.
Stainless steel precision
The EG barrel is made from stainless steel rather than the brass or aluminium used for many stock barrels. Stainless steel is hard and resistant to accidental bending, so the bore stays straight even if the front end of your replica takes a knock, and it keeps its accuracy without relying on a coating. The 6.03mm tight bore gives the BB a close, consistent fit as it travels down the barrel.
Upgrading the Masada
The PTS Masada is a modular, modern-looking rifle that many players run as an all-rounder. Swapping the stock inner barrel for a precision stainless steel one helps it shoot more consistently and makes it easier to tune the hop-up for heavier BBs.
Fitting
Fitting means stripping the replica, moving the hop rubber onto the new barrel and reassembling. When you fit your hop rubber, check that it seats correctly in the hop window and that the nub lines up, as some hop rubbers and nubs fit differently from barrel to barrel. If you are unsure, ask a technician to fit it for you.

Compatibility
Made in the 318mm length for the PTS Masada. Check your current barrel length before ordering, as different versions and builds may vary.
Before buying, measure your current inner barrel or check your replica’s manual, as length is critical: a barrel that is too long can protrude beyond the outer barrel or flash hider, and one that is too short may leave the BB unsupported in the outer barrel. Check that your hop-up unit and rubber are compatible with a standard Tokyo Marui-type barrel.
Care and maintenance
Before fitting, run a cleaning rod with a soft patch and a drop of silicone oil through the bore, then dry it so no oil reaches the hop rubber. After that, clean the barrel every so often, or whenever accuracy drops off, by pushing a dry or very lightly oiled patch through from the hop-up end. Always use good quality, seamless 6mm BBs, and never fire dirty or damaged BBs, which can scratch the bore or jam in the hop-up.
Who is it for?
Ideal for PTS Masada owners who want more consistent shots from a straightforward barrel upgrade.
Please note: Fitting an inner barrel requires partial disassembly of your replica. Check your site’s power limits after any internal change, and always wear eye protection.
