Such small pieces of metal and they cost around Php-400 to 600.

In the Gear-Box, specifically the Gears it should be no surprise these are made with Zinc-based die-cast metal, while the Steel-aluminum alloyed ones are a separate Php2,500-3,000. These gears are expensive, they should be since to cast them you need 1600Celcius while Zinc is 420Celcius. (then there is the matter that I work in manufacturing of Steel Furniture and workstations, so I have an idea what kind of machining tools makes what).
The Bore-up. So I’m told is the cylinder, the piston, and piston head. As I’ve learned, as with other things it determines the piston stroke which affects what kind of barrel the gun can use. Basically, the actions piston pulling back has a sucking affect for a fraction of a second. A longer barrel will have the BB still in it when the sucking begins.
I visited Philippine Airsoft today. I asked if they can install the parts I purchase, and they will for no additional cost. As the legal carrier, their prices are legal and more expensive. I met the Gunsmith Tim and asked him a number of elementary questions about gear boxes. Having more than one gunsmith explain these things to you is important as well as reading up on the matter.
My Future costs if I choose to upgrade my G3 back to [email protected].
I found out that my barrel is NOT 509mm but 469mm. In fact my gun is supposed to be for A2 barrel (509mm). Craptastic, If I’m going for a new barrel, I might as well go 530mm. The gunsmith tells me it will cost 3000! Although I don’t know if we’re on the same page. I saw a 550mm selling for 2,200.
Checking where my 469mm barrel ends, with my Cleaning rod, Tape measure. I notice there is an allowance of 84mm. Thats enough for 553mm! I can hold a 550barrel.
Taking my extended flash-hidder, I have an increased 141mm to my barrel capacity to a total of 610mm.
Although thats 2,200 for the 550. 🙁 At least I can buy it and the guys install it. Its upgrading a bit at a time. As I can afford it.
Then there is the spring. That is cheap over there and they will install it for you. I can use SP130 and a long barrel of 550 will cost me 2200. I also have to sell off my systema barrel of 469mm. Where am I going to sell that? That is going to be a bad hit. If only I can sell it at half its original price: 900.
