Moderator adapter Best Fittings Air Arms S300/S400/S410 10.0 mm

This moderator adapter by Best Fittings, enables you to put an 1/2” UNF male thread on your Air Arms S300/S400/S410 and other unthreaded barrels with a 10.0 mm diameter muzzle.

The adapter has a total length of 55 mm and slides over the barrel, after which it's secured by two flat grub screws. Because the adapter slides over the barrel, it only increases the total barrel length with 15 mm.

The Best Fittings moderator adapter has a matte black finish and comes supplied with a thread protector and allen key.
