Changed hop rubber, drastic fps drop

If you pull the upper off the gun, look at the front of the nozzle, there should be a half moon notch that points down toward the magazine.

PS looks like your TM didn’t get any fairy dust ATM ?

Yeah

I noticed that crescent shaped cut out

and it is facing down towards the magazine ?

Id best put up a “wanted” ad for fairy dust then ??

Nope! ?

I never did any of the aforementioned inner barrel tests, so more stuff to look at next time it’s apart. ?

It does have a stainless barrel, and unless it’s different to the Scar L , I believe they come standard with a brass barrel installed?

The inner certainly went back into the outer without any fuss or hints anything was bent.

I dunno about anyone being inside the gearbox previously 

I’ll see if I can get any clues without letting the fairies out of their captivity ?

if it's a stainless barrel definitely not stock the NRGs come with brass barrels. the fairy dusty falls out when you change parts. I was out this weekend with 1 degree temp i could get out to the 60m targets on the range with 0.28g in stock NRG 416.

If your gun is stock internally and fps is consistent +/- 4 fps then I’d look closely that the barrel, mags and ammo are good and clean.

IDK what nub and bucking you are running but it’s always best to have a perfectly performing stock gun before trying ‘upgrades’.

Throw a stock TM bucking and nub in for a baseline/fault tracing.

It still has the standard bucking & nub fitted. 
I think I’ll just remove the G&G rubber that I’ve installed and source a fresh TM one ?
