I was inside my VSR's hop-up chamber today trying to add some aluminum foil shims(TM precision unit, if that makes a difference), noticed the little divot in the hop-up arm, and recall thinking to myself "huh... You could probably fit an AEG hop-up nub pretty snugly in there...".

I've also noticed that the rifle doesn't seem to hop heavier BBs too well (I stick to .28s and .3s mostly as a result), so I'm very curious to see what results you get with the addition of a nub. Currently, I have to go back in and take out the shims anyway, as I did something wrong and now my shots are curving right. :

Thread bookmarked.

I also found that my TM Precision Chamber had a hard time hopping .30's, even then they weren't reaching their maximum potential. I noticed that the "fangs" weren't as long as the ones on my stock JG arm. I replaced the arm, and got a bit more hopup.

Hey Rick, thanks for pointing that out. I always figured that the TM precision chamber was the the "top of the line" VSR hop-up chamber out there. Haven't heard much on the PDI and I don't see too much raving going on about the Laylax NEO. I could just have missed it at some point though.

If all I need to do is replace the arm to get a bit more hop, I'll probably be scouring eBay relatively soon. Though I'm still curious about sticking a nub in there and seeing how it goes.

Why scour eBay? I'd be willing to bet someone's got a stock JG arm that they would be more than happy to give you at a game.

As for the different hopups on the market, I was never impressed with my PDI chamber, and I've heard that the Laylax "air-seal" chamber is a waste, no better than stock and still can get leaks. I've also owned a Noobie's TDC kit w/ TruFit Bucking system, and although it gave me great compression, I was never impressed with it's performance. In my own opinion, the best combination is a TM precision with the stock bucking and a TDC modification, with a screw on top used to adjust the hopup rather than the lever style.
