How to Clean & Maintain a GBBR – Milsim & Airsoft Guide

As some of you may know we recently bought ourselves a GBBR aka a Gas BlowBack Rifle, and as for today we’re going to talk about how to maintain it for longevity and smooth operation.

Before we begin, don’t forget to subscribe by filling in the form on your right. This way you’ll stay notified about all our new videos, blogs and Monthly giveaways. So that said, as the GBBR users amongst you may know, it requires more maintenance than an AEG. 

When to clean your GBBR

In general the rule is that if the system is getting more resistance which you can feel by pulling the charging handle, you need to clean it. How often to clean it depends on where you use it and how you use it. We made a general rule to clean it every 1 or 2 events just to be safe. 

Why clean your GBBR is important

If you don’t, the system will function poorly and you will create more wear and tear and eventually something will malfunction. By the way, this also counts for a GBB pistol, so if you require a guide for that as well, go check out the link we’ve placed at the end of this blog.

Cleaning your GBBR

Disassemble the GBBR

The first step is to disassemble the gun. Do this by separating the upper receiver from lower receiver by removing the pin above the pistol grip in the lower receiver. Once this is done you can rotate the upper receiver 90° and then you will be able to remove the front front pin as well. After that’s done you can take out the charging handle and the bolt.

Cleaning the parts of a GBBR

Next up, clean the charging handle and the bolt with a rag until cleaned dry. Do the same for the inside of the upper receiver and for harder to reach spots you can use Q-tips.

Lubing your GBBR

Products

Now that you’ve cleaned everything it’s time to start lubing, for this we recommend you to use “Teflon Gun Grease” or “Heavy Silicone Oil”. Because other oils may harm your rubber parts. Use a clean rag to smear the charging handle and the bolt with either the grease or oil. But remember not use too much, or you’ll make a mess. 

Additional Care

When it comes to the whole trigger mechanism and buffer tube, you can clean it if you want. But most of the time that won’t be necessary as it doesn’t get as dirty as the bolt does. If you have cleaned it anyway, you can use heavy silicone oil in order to lube it again.

Now that you have cleaned and lubed everything it’s time to start reassembling your gun.

Reassembling your GBBR

Do this by placing the upper receiver canted onto the lower receiver, and push back in the front pin.

Once that’s done you will be placing the charging handle and bolt back into the upper receiver.

Then close the system and lock it by pushing back in the back pin.

Spreading the lubricant

Next up pull the charging handle a few times in order to spread the grease or oil inside the system.

Longevity maintenance for your GBBR

Nozzle seals

Let’s talk a bit about extra maintenance tips for the longevity of your gun.

Spray some silicone oil into the nozzle of your magazines and bolt, after a few times of usage or when you’re about to store your gun for a long period of time, so these parts stay well lubed. If you do so, make sure to shoot a coupe of times with every magazine you’ve lubed, to remove the excessive amount of oil. But make sure to put off your hop-up unit so it doesn’t absorb to much silicone oil.

After you’ve done that make sure to clean your inner barrel, and if you don’t know how, check out the link in the below this blog.

Magazine usage/storage

Lastly you probably already heard people say that “a GBBR is only as good as its magazines”. For this we have some tips as well.

If you are using green gas magazines you want to keep them fully pressurized in order to prevent leakages and this way they will last you for years.

For CO2 usage, you overall need to lube the system more often. What can help is to place a drop of silicone oil on top of the cartridge before inserting it, this way the gun will be lubed when you’re shooting. Unlike with green gas you want to remove the CO2 cartridge otherwise the pin will deform into that specific cartridge and when using other cartridges your system will leak.
