This is a highly debated subject, with research to backup both claims. But let me give it to you straight up.
No.
Here is why:
UTG is an off-brand company, a Clone*.. If you will. They make weapons/gear in a mass production in the cheapest possible fashion while still giving the average joe an idea on what the actual things are like, this brings both good and bad things to the table, the good being that it shows kids exactly what can happen while trying to perform the tasks of an airsoft sniper, it teaches them something of patience, and shows that you don't need to have 6 high caps to drop a kid. However, it brings a bad taste in snipings mouth because the range of these rifles are just that of a weapon just a tad better than say.. A stock TM, or any stock AEG for that matter. Which means 75% of the time, you'll find that you can outrange the kid, and thus beat them. However that other 1 in 4 chance, he'll lace you farther than you can dream of. This puts a bad perspective into the snipers eyes because they think that all weapons perform this way, and thus.. They attempt to upgrade their cheaply mass produced Clone*.
Now, back onto the clone subject, and the subject at hand really.. A clone really can only handle factory standards, the trigger assembly is made out of the cheapest plastic you can possibly make, and the cylinder and other metal components are made of the lowest pop metal* you can possibly find. The weapons are also tested and rated to be able to fire only what they produce. So in theory, yes.. You could get it to shoot in the 500's.. easily. However after anything from 3000 rounds, to even your first shot. Expect that trigger assembly to break, which means you have one of two options.. Replace it for $45, or buy one that'll withstand it for $120 (A Zero Trigger). Then once you've done that, you'll find that you no longer have a safety, and you'll also find that your bolt handle will more than likely shatter from the cylinder.. Because chances are.. You haven't properly been recycling your rounds (Unlike the real military, in airsoft. You need to have your thumb over the back square like piece, to support your cylinder and not put any unfair pressure on the piece itself.. Most newer snipers will usually grab right onto the extension of the bolt (The actual handle) and fly it back).
Anyways, if you want it shooting in the 500 FPS with a .28 (Roughly 560ish with a .2... I'd guess). Then you'll need to do some serious upgrading and modification, and doing it on a Clone* is just something that you will find having more and more problems with, than say.. A Maruzen or a Classic Army.
Clone*: A cheap mass produced Knockoff brand style of weapon, they usually attempt to "Clone" already made, but more expensive weapons, and use cheaper parts and mass produce, to be more available to the general market.
Pop Metal*: A style of metal that uses scraps from various different pieces of metal, and melts it down and reforms it. This is very unstable metal and isn't reccomended to handle anything high stress/high intensity.
No.
