Airtech Studios IBS Inner Barrel Stabilizer for G&G CM16 SRS 7″
Made for the G&G CM16 SRS with the 7 inch front end, this Airtech Studios IBS clamps the inner barrel in position at the muzzle so it cannot shift around inside the outer barrel. It is a simple way to improve consistency on one of G&G’s popular short-barrelled M4-style rifles.
Airtech Studios is known for practical, well-thought-out upgrade parts and accessories for popular airsoft replicas. The IBS is one of its best-known products: a small part, made for a specific model, that addresses a common cause of inconsistent shots.
Why inner barrel movement matters
In most AEGs the inner barrel is held at the back by the hop-up unit but is only loosely supported at the front, inside the outer barrel. That leaves room for the tip of the inner barrel to move slightly, and any movement at the muzzle or hop-up end can send the BB off on a slightly different line each time. The result is a wider group and shots that wander for no obvious reason.
How the IBS works
Airtech Studios designed the IBS to lock down the inner barrel and stop it moving at the muzzle end. It fits at the front of the outer barrel and holds the inner barrel centrally, so it stays in the same position from shot to shot. Because it is shaped for one particular model, it fits that replica’s barrel assembly properly rather than relying on tape or shims.
Fitting
To fit the IBS you will need to remove the muzzle device and reach the front of the inner barrel on your CM16 SRS. Follow the instructions supplied with the part and take your time, noting the order in which parts come off. If you are not confident working on your replica, ask a technician to fit it.

Compatibility
This IBS is made for the G&G CM16 SRS 7″ only. Airtech Studios produces different IBS units for different replicas and barrel lengths, so check your exact model and version before ordering. If your replica has been fitted with an aftermarket outer barrel or a different length inner barrel, the fit may differ.
Care and maintenance
Whenever you strip the front end of your replica, check that the IBS is still seated correctly and that its O-rings are in good condition. Worn, flattened or missing O-rings reduce the grip on the inner barrel, so replace them when needed; Airtech Studios sells spare silicone O-rings for its hop-up and inner barrel stabiliser assemblies. Clean the inner barrel regularly with a cleaning rod and a lightly dampened patch, and avoid heavy oils or grease around the stabiliser, which can attract dirt.
Who is it for?
This IBS suits owners of the 7 inch G&G CM16 SRS who want tighter groups and more consistent shots, particularly on short-barrelled builds used for CQB and mixed sites.
