mG36 is ready

On thursday a guy from my favorite airsoft shop called me and we spoke for a while about my mG36 replica I sent for repairs and tuning.

He said that he installed the parts I asked for (precise inner barrel, 6.04 mm by Systema, and sealed air nozzle) and tested the replica on the chronograph. I wanted the replica to have around 350 fps -- enough for playing with guys that have 400 fps installed, but not very much). And I thought that after this barrel and nozzle installed it’ll have something close to that (330...340 fps maybe), since the G36 from Classic Army has 315 fps in stock!

Do you want to know what were the results from chronograph? A shitty 290 fps! I was stunned when I heard that.

It seemed that there was no other choice than to change the power spring. I asked the guy what caused such poor results. He said that the cylinder - cylinder head - piston head set is not very airtight and the spring looks weak. He suggested to change the spring go M100 and new cylinder with both heads made from aluminum. When I approved those parts to be installed, he asked me if I didn’t want to have the M110 instead as it’ll give me something close to 400 fps. Of course I agreed...

On friday he called me again. He installed the M110 and the other parts I mentioned above. He checked the replica on chronograph again and had result of 390 fps. That’s more than enough, I think...

Would you guess how much I’ll be charged for this tuning? PLN 460, amount equivalent to $170.

But hey, if the mG36 is supposed to be an light support weapon (as it’s real steel MG36 counterpart), it must have better range and accuracy than typical ASG replica...

Junk tuning

Long time, no see, huh? I didn’t attend any airsoft game for two months, so there’s nothing to write about. But when I’m not playing airsoft, I am thinking about it. So this is what I found out lately.

I mentioned here, that I have my AUG tuned. It has Guarder M110 / SP110 spring, helical gear set, full set of cylinder / cylinder head / piston head (bore-up) and some other stuff. This left me stock Classic Army spring and stock cylinder with two heads.

I am curious if I can use the spring to tune my AK-47S. If this Cyma replica is an exact copy of Tokyo Marui’s one, then I guess there’ll be some trouble with the piston / piston head / spring. As far as I remember, the TM’s piston is permanently connected to it’s head, so to change the spring you have to do something with piston / piston head. I don’t know exacly what needs to be done, i.e. if I need to have spare piston or not.

I also have one 170% CA spring, which is similar to M110. I think I’ll put this spring to the mG36, ’cause it lacks good range for being a support weapon. I’ll put it inside along with sealed air nozzle I bought a year or two ago and didn’t have time to install. ;)

mG36 phase III upgrade - day one

Today I decided that I'll install the parts I receieved yesterday, ordered earlier this week (stock, barrel), the sealed nozzle I bought few months ago and a 170% Classic Army spring I got with my replica.

I decided that the first thing to replace will be the stock because that was my main purchase. I tried to remove the original stock in order to attach my new purchase. I didn't have the proper hex key to remove the hinge. So the stock will have to wait for it's turn.

This was not a good day for the G36 tuning. First of all I didn't have all the tools required for such a work and I ordered parts that didn't fit my replica well. ;)

Since I removed the gearbox and magazine socket to see how to attach the stock wiring to the gearbox (I still have no f--king idea!) I had an opportunity to remove the inner barrel and install the precise one. So I removed the outer and inner barrel and the entire metal part that holds the hopup together. I dismantled that part and the hopup itself. When I got my hands on the barrel and compared it to the one I bought (designed for M14, not G36!) I saw that it has the vertical incision (that holds the barrel in place and doesn't allow any motion in axial direction) was in different place. This means that the barrel is not properly connected to the rest of the replica.

Without having the stock installed I didn't want to replace the inner parts of the gearbox - i.e. nozzle and power spring. This is because I wanted to have first the 9.6V battery installed which I can't install without the stock.
