What upgrades can be done on a GBBR?

Recommended Posts

Hello everyone, a while back, I bought several hop-up buckings for my AEG to see if they really made a difference. I fell in love with the Promethius Soft type bucking and was wondering if I could use it on my We-Tech 416 AKA: M4-SOL considering the fact that GBBR's have different mags and they feed differently. So here are my questions:

What upgrades can be done on GBBRs? Thanks!

You can upgrade a lot of parts on a GBBR, varying by model or brand.

 

However, what they affect is something you have to carefully consider. Put in something and you may experience faster wear or functional problem.

 

Here are some examples of parts that you can usually find aftermarket replacements for:

 

- recoil spring

- buffer

- trigger & trigger grouping

- sears

- inner barrel

- hop-up unit

- bucking

- externals

- bolt & bolt carrier group

- rocket valve (or whatever name, inside the bolt)

- NPAS, if you want that type of FPS adjuster
