EpeS M249 Hop-Up Chamber

The EpeS M249 Hop-Up Chamber is a very good quality Hop-Up Chamber for the M249 of various brands of airsoft replicas.

This chamber is particularly suitable for Hop-Up buckings with a standard lip length. With Maple Leaf buckings, for example, the length of the lip is slightly longer, which can cause the lip to end up in the feeding tube, resulting in feeding issues.
For this reason, these chambers come with various washers so you can use them to make the bucking fit less in the feeding tube.

With the rotation wheel you can adjust your hops perfectly.
Furthermore, this chamber is CNC-machined for perfect quality.
