Still no suppressor but nice job!

You can make an adjustable rear sight with a bolt, three nuts and some epoxy

I have a short question - is it dangerous to grease my airtank(200 bar) with silicone grease from inside to prevent it from rusting

I'll be straight up and say I don't know the answer to that exact question, at least not well enough to be certain. I suspect it's not dangerous - but then again, weird things can happen at high oxygen concentrations.

However, I do have another solution - only fill the tank with dry air. Many 200 bar air sources already have a water filter built in but, even if yours doesn't, it's probably possible to add one.

Technically the concentration doesn't change, the proportion is the same even if you compress it. It should be safe.

Proportion might be the same but more of it occupies the same volume so I wouldn't say it's as safe. Similarly when you draw vacuum in a container you can stop things from burning (f.e. lightbulb filament) - proportion is the same but there's just less oxygen

I'd define shoving 200 times more oxygen into the same space as more concentrated, even if it's still in the same proportion to nitrogen. I know the buffer gas is an important factor and I'm pretty sure the whole thing should be outside flammability limits (after all, hybrid mixes that are more than slightly out often won't ignite).

However, between adding something to the tank (no matter how safe it "should be") or the unquestionably safe standard practice of removing the moisture, I'd put my faith in the latter.

That's true. Still, found this, it seems an issue for pure oxygen but not compressed air.

[quote="bahur47"]warhead052 - I'm from Bulgaria and here, in almost every online weapon store there are HATSAN 125 barrels for 22 euros and HATSAN AT 44 for 40 euros ( 125 is for break barrel, at44 is for pcp)

Dont you need special documents to buy a barrel ? Please post a link with a barrel for sale.
I am looking to put my hands on a 4.5 , 5.5 mm barrel for a long time. There are not for sale in Romania, and if they are you need docs. and police autorization................

Here in Bulgaria you dont need permition to buy air rifle. You only need to registrate it in the police if its 24+ joules, so there are no limitations on air rifle barrels either, but for firearm barrel - you need a document. Here's a link http://www.pushka.eu/product/Spare-part ... -44-4.5-mm .

Also thank you guys for answering my grease question.

Are you freaking joking with me or that site sells blank firearm cartridges??? Then as Bulgaria is inside EU the customs won't check the packages... Then all I need it's a barrel and machine some bullets... I must be dreaming just yesterday I was think about getting a .22 now looks like I have a bigger range of good to choose.

Actualy someone from my country had been put on charge for buying a airgun from Bg. - He went to police to register it and its power was 300 mps ( in Ro guns over 220 mps are considered firearms) plus it was expedited with a fast expedition service ( without respecting the policy regarding importing guns). Stupid lows in my country ! Even to buy lead pellets is a bit of a problem.

Just because there are no customs charges, it doesn't mean that goods aren't inspected.

I bought all my airsoft good from Spain and Poland.
In Portugal according to the law airsoft guns needed to by painted but not in Spain and Poland so all the guns arrive with original paint without any problem, as soon as they are shipped by a third party transport, not national service.
