This custom machined metal end cap has been designed to close fit and replace the factory delrin end cap.
The machined end cap has an O ring mod which helps guide and centre the barrel.
It also provides additional support to the barrel from the standard setup of just 2 bushings which are used to clamp the barrel in place.
This mod is highly recommended for those users who have upgraded to the "Extreme-Flow Valve with Assembly" or any setup which is spitting out slugs at higher speeds.
It helps gain accuracy by providing more stability and the results can be seen at long range shooting.
Model Check: These are machined to fit .257 barrels with an OD of 14.2mm
