Banish Fixed Barrel Spacer Features The Banish Fixed Barrel Spacer replaces the internal spring found in the Nielsen device of the BANISH 45 a change that is necessary whenever the suppressor is mounted to a fixed barrel firearm rather than a traditional recoiling barrel pistol. The Nielsen device is designed to allow a pistol s barrel to cycle independently of the suppressor but on fixed barrel platforms that movement is unnecessary and can actually work against reliable function. Swapping in the fixed spacer locks that mechanism in place giving the suppressor a solid stable mounting point suited to hosts that do not have a moving barrel. This makes the spacer a required accessory rather than an optional upgrade for certain suppressor hosts. Aluminum construction keeps the spacer lightweight while a black anodized finish protects it from corrosion and wear over repeated use. It is commonly needed on popular pistol caliber carbines and subguns such as the Sig MPX CZ Scorpion and Kriss Vector all of which run fixed barrels that benefit from this configuration. Installing the spacer is a simple internal swap within the BANISH 45 s mounting hardware rather than a full suppressor teardown. For BANISH 45 owners who are configuring their suppressor for a fixed barrel host this spacer is a necessary and straightforward accessory available for sale at GrabAGun.
