Additional/replacement threaded adapters which mount to your barrel, and provide an attachment point to the NateChrony.
Standard adapters have large, easy to grip tabs, making installation and removal easy for all hands, and in all weather conditions - i.e. with gloves on!
Slimline adapters have reduced sized tabs for bullpups and where clearance between the barrel and tank is at a premium.
There are 2 adapters in each package.
