4UANTUM MAGNUS PRO AR15 Hop-up Bucking Sleeve – Black

4UANTUM MAGNUS PRO AR Hop Bucking Sleeve
Are you looking for a way to increase consistency and accuracy of your GHK or VFC AR15 GBB rifle? Are you dealing with deformation or shifting of the hop-up bucking affecting the flight path? Do you want to replace a worn or damaged sleeve? Then the MAGNUS PRO AR hop-up bucking sleeve by 4UANTUM is exactly what you need. This precisely manufactured sleeve fits directly over the hop-up bucking and ensures its firm position, proper centering and stable pressure in the MAGNUS PRO AR chamber. This reduces inconsistencies caused by bucking movement or deformation and improves air sealing. The result is more stable performance, repeatable accuracy and higher reliability, especially when using heavier BBs and higher power setups. This is a replacement part for the sleeve included with the original MAGNUS PRO AR hop-up chamber.
