Need Tips for My First GBBR Build

[LzChase]

I'm working on a GBBR build, based on a WE HK416.

 

I've never worked with GBBR type weapons before and there are some things I'd like to know.

First of - the RA-Tech Steel Bolt Catch & Trigger assembly. I don't live in the UK but this is the forum I prefer to use. I live in Sweden.... which is a big problem for an airsofter. Spare and Upgrade parts are very hard to find here and RA-Tech is pretty much unheard of in stores. What would be a good way to get these parts?

 

Another thing is the inner barrel. The outer barrel has been changed to a 190mm mock suppressor. Does the suppressor need to be modified to support the inner barrel?

Then there's the way too common issue of optics. Do budget-friendly optics for such a build even exist? A really cheap red dot or scope would obviously at best work for a few days and fall apart after a few shots at worst.

There's also the signature buffer tube-mounted stock of the AR type rifle. Do all aftermarket stocks fit? Or do I have to ask the retailer before ordering?

And finally, should this gun actually have a mock suppressor? Or does it put too much weight on the floating barrel?

 

The idea is to build a DMR. What parts can be used to increase accuracy?

 

General build tips overall are also much appreciated.
