How to check upgrades

Before I start taking my Bar-10 apart for the first time, is there any advice to be had in terms of identifying aftermarket parts and upgrades inside? Serial numbers? Logos? I need to find out what’s actually been put in my gun and it’s been long enough.

 
Probably your best bet would be to just take a photo of all the bits and drop them here. Can't imagine we'd have too much trouble IDing it all.

 
Calling @Samurai 

but im pretty confident that if there is a screw in the back of the pull handle, you have to remove that.

sorry some of the pictures might look pointless, but they're also a way for me remember what came out where when it comes to putting it back together again :P

 
That makes sense. Have you had a look on YouTube for a dissasembly guide? I never take someone apart without having a look at a video or an exploded parts diagram first.

Yeah I was watching one for removing the hop, but he seems to just slide his straight out.

I know he says it's tight, but I can't see what's stopping mine and it's just not budging beyond 5mm wiggle room either way

Ok, he made that look incredibly easy, have you tried twisting the hop unit before pulling it? Push it slightly to one side and then give it a good tug. 

Knowing who did your upgrades, I wouldn’t be surprised by if they glued it in place. They are shockingly bad at doing any work. I actually learnt to do tech work of any kind from there multiple cock ups they made, had to learn to do it properly.

It does move somewhat (at least the hop unit seems to move a little, although feeling the end of the inner barrel from the other end, that stays absolutely fixed)

 
That’s probably because it’s been spaced, just give the hop unit a little tug, and it’ll bring the spacer along with it.

 
Long screwdriver helps. Flathead ideally and put some tape or tissue on the end to cushion it against the hop unit a little.

Use a hammer to tap it. Move the screwdriver around the circumference as you do this as that'll make it come free more easily if it's a bit too snug. If nothing happens tap harder heh.

Edit

Also so far I see:

- Airsoft Pro trigger (whoda thunk)

- Stock hop unit

- Potentially an aftermarket cyclinder

- Aftermarket barrel of some description

^This, or a pair of needle nose pliers and use them the other way round. It’s a bit of a bodge but can work. 

 
I had the same problem on my Bar 10 - the hop unit was very tight - and i could not get it all the way out - i  had some barrel spacers causing  friction making it harder than it should have been, but i just push the hop back in place - and wiped the inside of the outer barrel with a cloth and a bit of silicone oil that was enough to make it a lot easier to push out, but also be careful where the screw that holds to end barrel on caused a small dent on mine that also stopped the hop unit coming out

Stock hop unit on a “fully upgraded” sniper? Is it generally regarded as a good hop system? The main issue I’ve had with it has been double feeding.

What have they put on that?!

To be honest, that’s probably your issue, my brother sent his DMR into same shop as you Ash, and it came out with a split bucking covered in silicone oil....

Edit: You say it’s fully upgraded, have they Rhopped it? I’m not sure on what make and brand that hop rubber is, but I wouldn’t say it’s “upgraded” looks stock to me.

Yeh, if that oil has been sitting on the bucking for that long I'd just ditch it.

Also look over the barrel. Looks like it could be a PDI one given the location of the etching.
