Airtech Studios IBS Inner Barrel Stabilizer G&G ARP9 & 556

The Airtech Studios IBS Inner Barrel Stabiliser G&G ARP9 & 556 is a fairly simple upgrade that will ensure your ARP will shoot even more precisely.

By installing this stabiliser, it prevents play between the inner and outer barrel and thus provides more precision that is almost immediately noticeable. The bullet trajectory is thus less affected, making the grouping of the bb's more compact.
