Dear All
We produce airsoft gun custom part and some other related products, here is our website, www.modify.com.tw
Also, there are few more products still in the developed process.

Here is new product information:
1) We named this gear set SMOOTH, in which it included 6 pcs of 7mm ball bearing inside, so that even you use it on a 6mm gearbox or a TM (6.1mm) gearbox, you could upgrade you gun with a 7mm ball bearing performance.

2) It is PRE-SHIMMED. Compare to Modify Modular Gear set - Bushing type (Version 1), the SMOOTH is fixed on 1 piece of bracket. It's compatible with most Ver.2 and Ver.3 gearbox, including the reinforced Ver. 2 gearbox, like Systema, CA, G&P...

3) As you know, owing to the tolerance, the fixed position holes for the gear set on some brand gearboxes (such as Jing Gong...) are a little different from the stock gearbox. The Modify SMOOTH has a ARC-shaped hole on the bracket. It allows the bevel gear to be adjusted slightly for fixed position to compatible with the different brand gearboxes.

4) Each gears of the SMOOTH could be assembled and disassembled by a special tool. You could use our special tool to maintain the SMOOTH, change the gears, ball bearings and bushings...

5) The SMOOTH included: 1) Modular Gear Set with 7mm Ball Bearing, 6 pieces;
with Stainless Bush (6mm/6.1mm/7mm) , 6 pieces;
