The IBS™ Inner Barrel Stabilizer Unit is designed to lock down the gun’s inner barrel to prevent any axis movement at the muzzle and hop-up end which may cause major deviations and inconsistencies on the BB’s trajectory. Once installed, your rifle performance will noticeably shoot straighter and further with a proven improvement in groupings. This is one of the easiest yet most effective upgrades you can have for your rifle! The IBS™ is a simple, yet highly effective drop-in upgrade for the G&G ARP9 & ARP556 and is designed to be easily installed by yourself. An essential upgrade to give that extra competitive edge against your opponents. Make your shots count when it matters!
