ZCI 6.02mm stainless steel inner barrel (263mm)
A precision tightbore upgrade for your AEG. This ZCI barrel is machined from high quality stainless steel with a polished 6.02mm bore, tightening the gap around the BB to reduce air wastage for better compression, accuracy and consistency.
Why a tightbore helps
The stainless steel construction adds weight and rigidity to minimise vibration, while the smooth polished bore lets the BB travel cleanly. An O-ring at the muzzle end centres the barrel within the outer barrel and dampens vibration for tighter groupings.
Length and fitment
At 263mm this barrel suits carbine-length AEG platforms. It is Marui-spec and drops into standard TM-pattern gearboxes and hop-up units with minimal modification. Check your existing barrel length before ordering. See more airsoft accessories.
After fitting
A precision barrel can nudge your output higher, so chronograph after installation and adjust hop and spring to stay within your site limits. Our Kent repair workshop can fit and test it for you.
