Description
The LAYLAX Prometheus EG Barrel is an inner barrel for airsoft rifles, supplied here in a 363mm length with a 6.03mm bore. It is listed for Sopmod, M4A1, SR16 and SG551 platforms, so it can be used when replacing the barrel in any of those models.
Because it is an internal part, the barrel sits inside the rifle and the upper receiver has to come apart before it can be swapped. Check the 363mm length and 6.03mm bore against your own build, along with the hop-up unit your rifle uses, before ordering.
Fitting means stripping the upper receiver, taking out the existing barrel and refitting the replacement, so it is aimed at someone already comfortable with teardown work or at a technician carrying out the install.
