That was it for our findings regarding the NGRS models, now let’s talk a bit about upgrades.

These days upgrades are kind of standard when you buy a new gun and we already had some questions of you guys asking what pieces you best change from these models. Our recommendation when it comes to this is to not do anything. Except maybe the lipo mod to save you from buying the expensive Tokyo Marui batteries.

For the rest, run it as it comes and if you want to do some upgrades, keep it to an absolute minimum. The more you mess with them, the more likely you will have some problems later on. Due to them being such a complex system. They are already amongst the higher-end guns on the market and they have their reasons to be amongst the best ones as well.

Also if you don’t have any experience taking apart an NGRS gun, don’t try it yourself because there’s a high chance you break something or put something back together wrongly because it’s such a complex system. Have it done by somebody who has a lot of tech experience on these kind of guns.

1. FPS UPGRADE

If you want a higher FPS output you will require a special spring for the NGRS series. For example the M 100 Eagle6 spring. Which will give you an FPS output of about 350 FPS with 0.20 gram BBs. We do however recommend you to use 0.28 gram BBs if you do the upgrade.
