Piston + Rack for dboys M4 CQB???

cursai

Does anyone know what teeth number is best for DBoys M4 Cqb. The teeth on the one i had have worn off. (better than the gearbox cog breaking i guess). it was a fourteen tooth rack. I cant seem to find any for sale!!!
Ones i have found are seven steel and seven plastic.
There are of course fifteen teeth ones that have 3 steel teeth.http://www.ebay.ie/itm/SHS-NYLON-POLYMER-PISTON-3-TOOTH-V2-V3-AIRSOFT-/120765620964?pt=UK_SportingGoods_OtherSports&hash=item1c1e3122e4#ht_1160wt_1029 Would these be safe or good to use?

use one of these. i use them quite a bit and i have to say they are fairly bulletproof!

Good question Dinny. Was wondering that myself. Someone told me that the inner cogs in the gearbox might get torn or put under told much stress.

thermo

never had any bothers with one of these personally..............
