Sneaky

Also, understand where all thes parts come from, but I am a big fan of supporting the UK businesses here and to ensure that they keep going.

I used to import in the past when; It was better times A very good exchange rate. I wouldn’t either bother now.

Very true. Something to bear in mind - having the correct cylinder is right, but also attention needs to be made to the quality of the piston head rubber. This tends to be forgotten. Learn from what you have found out so far, but when it comes to upgrades, like is more and bit at a time.

As above. Have you tried installing some of the original parts, bit at a time? Process of elimination, takes time but worth it.

I would recommend an R-hop for a DMR build, works well and is very consistent. Does the air nozzle has an internal o ring? There should not be that much of an fps reduction with hop on, if you are having a 75 fps drop.

@ak2m4 would be the place to start off with.

Looks like a great place for airsofting pizzas! Eat and run! Or eat and shoot!

Change the motor if the issue persists after doing the above first.

Try all the above. Also remove the rubber o ring from the standard piston head and replace the ZCI o ring. See what happens there. There should not be much friction, any spring is designed to take into account of any minor friction.

Do it and see the end result….. start saving for a new RIF now….

Builds should always meet the requirements of .20g bb at your site. Once passed, you can use what ever bb, just make the finer hop adjustments.

At Red alert the arm bands stay in place, otherwise your asked to leave. Just means that all the players have to up their game with not being spotted, which is a challenge in its own right - and fun when it does work. The snipers in ghillies that I know do an exceptional job to be concealed and still follow the rules. Can’t see it being an issue…..

I think UKARA and your data is better protected than any government institution…. And pretty much everyone has your data, bit late to the party now, scary as it is! 🤔

Replace the hop unit, cheap and easy to do.

What kind of ETU do you have? Could there be something interrupting the sensors, which switches it to full auto?

Welcome to the exclusive club.

That’s good. Just hope that gremlin does not show it’s ugly head in the future!

I don’t own a GBBR, but will have a go at reducing the mag capacity for my NGRS SCAR H. Sounds like it was more immersive. 👍🏾

For my TM SCAR H, the only setting I have for full auto is the two round burst, as it is so accurate, why waste the ammo! I have not messed with any other settings for now, not even the pre cocking as I do not want to put any or stress on the parts and gearbox.

First time, I have ever seen that issue. Hope you get it all sorted.

I understand now, hmm…

Could be the piston. How well maintained is it? More information is needed really, also a video of the issue.

Why the drop stock, what do you want to achieve? I wouldn’t cut the tube from the back of the receiver.

Just turn up, as so much has change in regards to technology in airsoft, start a fresh! Otherwise follow all the above posts.
