Our take:  Shims are one of the most essential parts of any gearbox, ensuring proper spacing between gears to protect against wear.  This high quality, high-precision Lancer Tactical X-Mod shim set is a must have for any serious airsoft technician, allowing you to get the perfect angle of engagement for each gear in any type of gearbox.  Properly shimming a gearbox can result in a longer life of the AEG's gearbox, and improved consistency and performance.  Re-shimming is recommended to be done only by experienced Airsoft technicians.

Shim Set Includes:  11 x 0.20mm shims, 10 x 0.15mm shims, 10 x 0.10mm shims (31 total)

Lancer Tactical X-Mod Upgrade Part Series:  An Airsoft Megastore Exclusive
The Lancer Tactical X-Mod upgrade part series is an all-new line of Lancer Tactical parts manufactured and distributed EXCLUSIVELY by Airsoft Megastore.  The X-Mod series of parts are NOT to be confused with generic "Lancer Tactical" parts currently on the marketplace, as the X-Mod parts are NOT BUILT THE SAME.

Lancer Tactical is a leading performance part manufacturer, and Airsoft Megastore has engaged Lancer Tactical directly to manufacture the X-Mod upgrade parts, which are now exclusively available at Airsoft Megastore.

The difference between Lancer Tactical X-Mod parts and generic "Lancer Tactical" parts currently in the marketplace is a noticeable improvement in consistency of quality and an improvement in build material.  X-Mod parts are manufactured out of the latest and most advanced high performance materials with no shortcuts taken.  X-Mod parts have been contracted by Airsoft Megastore to undergo a 12-point manufacturing quality assurance test (at every stage of the manufacturing process) to ensure sustained high quality.

The results are quite noticeable:  Lancer Tactical X-Mod parts consistently out-perform the competition, and are on-par with the highest quality upgrade parts available on the market, but at extremely competitive prices that won't break the bank.
