RPS Airsoft AEG M4 Precision Gearbox Brass Shim Kit (30 Pieces) (GG09-11)

RPS Airsoft AEG M4 Precision Gearbox Brass Shim Kit (30 Pieces)

Originally created for our store tech staff to reduce time and sorting through random shims made from random materials, finish and sizing.

Shimming an AEG correctly is time-consuming.  Build with the best.  Save time, get better performance and move on to the next build.

Why real Brass?  Smooth, less noise, less heat.

30 brass shims per Package.

Made from 100% real Brass in the USA.
