This is the smallest, lightest and greatest accessory feedneck available and that we recommend for use with all of our custom gun bodies. Use it without the threaded insert adapter on all Inception Designs Autococker and Sniper based bodies as well as most Empire gun bodies that have the stepped feed stub milled into the gun body (Resurrection, Sniper, Vanquish, Axe). No adapter is needed to fit Planet Eclipse guns such as the LV, CS1, Geo, Ego, E-Tek, G-Tek, G-Tek R, Etha. Use it with a threaded adapter (available with the feedneck at a discount when purchased together) on many other gun bodies that are threaded for Empire/Smart Parts/ Indian Creek Designs, Angel (low and hi profiles available) or DYE. It has thumb screw adjustment with a milled adjustment knob for better grip, with an ambidextrous locking lever system. Locks onto the gun body or the adaptor with a small lip so it wont come off even if it comes loose. Ultra modern low profile (lower than the Empire Accessory feedneck). Lightweight. Machined from Aluminium 6061 T6. All feedneck adaptors are polished black anodizing (as they are hidden) except for the Angel Hi Rise which comes in the same finish as the feedneck selected.
