I'm very glad I got these. I bought this right after I bought a tightbore, but the tightbore hasn't arrived yet, so I'm JUST reviewing this on a stock, non-upgraded JG G3.
Before I got these, every few shots would veer to the left or right, but now they don't do that nearly as much.
There are still the every-so-often shots that veer in a bad direction, but they aren't nearly as common.
It's easiest to put them in by putting it on the hop-up arm and then pushing the hop up arm down into the hopup. This, or small pliers. It can be difficult to get in, because they're JUST BARELY the size that fits in. It makes it harder to move in the hop up, so maybe the first shot after adjusting it won't be any different, but it's a small flaw
Definitely buy this, but not JUST this (add it to another order so you don't have to pay $12 in shipping for these puny things)
Only $5 for more consistency, probably the most cost-effective way to improve accuracy.
Doesn't fit %100 perfectly.
White one doesn't look like it would help as much.
