GROT is easy to clean. The field stripping is tooless (firing pin stabilizer pin might be re- moved with the round). There are no "nooks' ‚ inside the gun or its internals and since the gas system is similar to AR-18, there is not much carbon buildup inside the gun. The barrel might be easily detached, so the cleaning of barrel extension is way more com- fortable than in AR-15 rifles. The disassembly is quick and the cleaning is easier than in classic AR. It does not require any specialized tool too. The barrel is attached in one point with a single buckle which is releasing the barrel. First disassembly required some more force to unscrew the buckle but then the barrel was released freely. It just happened once also in the "demo" rifle. Since the rifle which was used solely as a "show" gun has never been fired, it has not been dissasbled. To remove the barrel we had to use the broomstick - most probably the factory grease was the cause. But again, it only happened during the first gun break down. GROT has a slight flaw. To remove and clean the gas system, the barrel must be detached. Of course, this makes cleaning easier but if I would like only to clean or check up the gas system, I can't do that without the barrel removed. In the- ory, you could try to push out the gas piston by repeated charging but it will work only on the well-cleaned gun. In reality, to remove the gas system you need to remove the barrel, remove the gas regulator and turn the barrel muzzle down. In a perfect world the gas piston falls out, sometimes you will need to apply some force. Push the gas piston rod to the rear and release. It should smash the piston and release it. Repeat until the piston will fall out. After five smashes I was usually able to remove the gas piston. Pro tip: do not try to release the piston by hitting the muzzle end on the floor or desk as you may damage the thread or muzzle device as this may cause critical failure of the gun. Obviously, the gas piston and gas block in- ternals must be cleaned from time to time but only dry cleaned - no residues could be left there otherwise the carbon buildup will appear. Based on my experience, I can recommend dry cleaning of this part. Now something important for the owner of two barrels. If you will ever want to comple- tely disassemble all of the parts (with both gas FIREARMS
