Duane Posted February 26, 2020 Share Posted February 26, 2020 Good evening all: New to the forum here. Looking forward to the exchange of ideas and information. I just got a VR-80 and cleaned it before shooting. I used the ammo that is on the Rock Island site. Fiocchi 12 gage 2 3/4", 1 1/4 oz. 1330 FPS, 7.5 shot, and (250 rounds) the weapon preformed flawlessly. Broke the weapon down for cleaning and all went good except: the GAS RETAINING NUT (part number 70) unscrewed with no issue and then unable to remove the GAS BLOCK (part number 68) is stuck in place. Any ideas for my situation ?????????????? Link to comment Share on other sites More sharing options...
Nelsonh Posted February 26, 2020 Share Posted February 26, 2020 I use brake parts cleaner and wd40 to break up the carbon build up and scrub it clean work the piston a little at a time as you clean, maybe light taps with s soft mallet.Sent from my Moto E (4) using Tapatalk Link to comment Share on other sites More sharing options...
parvusimperator Posted February 26, 2020 Share Posted February 26, 2020 +1 on brake cleaner. Maybe soak stuff if it's really stubborn. Oh, and do it in a well ventilated place. Link to comment Share on other sites More sharing options...
Gunner_Freeman Posted February 26, 2020 Share Posted February 26, 2020 Did you remove part #67 the split rings? They will be under the gas block, you have pull back the bolt and the slide (#63 & #64) to be able to move the gas block to the rear to get to the split rings.

Duane Posted February 26, 2020 Author Share Posted February 26, 2020 The bolt and the slide (#63 & #64)are back and secured, gas block (part number 70)w ill not move it is "stuck" and will not slide down to expose and release the split rings.

Gunner_Freeman Posted February 26, 2020 Share Posted February 26, 2020 Ah, I misunderstood the problem, then my only other suggestion is if none of the other tips work, put it back together, go to the range dump like 2-5 rounds to get it nice and hot and then try to disassemble it as quick as you can right there at the range.

Nelsonh Posted February 26, 2020 Share Posted February 26, 2020 If all else fails put the barrel in your refrigerator or frezzer over night and get s tourch to heat the piston whole bumping it with plastic hammer. Cold well shrink metal and heat will expand. Use to install ak barrels this way by hand.I bet it's just heavy carbon build up tho.

LARUE Posted February 3, 2023 Share Posted February 3, 2023 Had the same problem with my new VR80. Made sure to lube the piston before shooting but when I got home to clean it. The piston was stuck inside piston shroud. Stuck stuck.... Soaked... free and clean now. Is this a common problem?? Link to comment Share on other sites More sharing options...
Nolan Posted February 3, 2023 Share Posted February 3, 2023 Do NOT lube the piston! Leave it dry, or you will have the same problem again. Nolan Link to comment Share on other sites More sharing options...
