The Jaeger Precision Alpha Arm is one piece and requires no hop nubs to be used. The arm has been designed over a long period of time and will work with any hop up rubber.

That being said you will benefit more from using a hop up rubber that has a large contact patch. We highly recommend the Sniper Mechanics Flamingo hop up rubber.

The arm is designed to perfectly mate up against the rubber and provide a large contact patch that boosts performance and stability. Because there is no nub involved there is nothing to shift in place so the arm is always solid and one piece.

This is the second version of this part. The original was hand made from Brass. This version is CNC machined from 7075 Aluminium and anodised in Red.

This part is made in the UK. You are supporting the original creator and small UK businesses.

There are two variants. The red arms are meant for heavy BBs and the orange arms are used for lower weights (usually below 0.4g BBs but different rubbers and setups will yield different results).
