Seraphim989 Posted May 19, 2011 Report Share Posted May 19, 2011 Take off your handguard and check the giant screw that holds your barrel on Quote Link to post Share on other sites
Spencerman Posted May 19, 2011 Report Share Posted May 19, 2011 As said above, most likely the grub screw holding the internal gubbings to the hop unit. Refer to page 29 of this thread for pictures and instructions how to get there and find it. Quote Link to post Share on other sites
kepp Posted May 19, 2011 Report Share Posted May 19, 2011 for the life of me i cannot get the nut to loosen im worried about snapping the body im turning that hard did anyone have the much trouble getting it off or any tips. so if these are noob questions. Quote Link to post Share on other sites
Seraphim989 Posted May 19, 2011 Report Share Posted May 19, 2011 It feels that way, I was worried about that as well, but you gotta just twist it Quote Link to post Share on other sites

Yeah, I was like that too, but dont worry the gun is built like a rock. Quote Link to post Share on other sites
calbur20 Posted May 20, 2011 Report Share Posted May 20, 2011 A rock made out of plastic and awesome. I've noticed that my bolt fails to lock back lately, anyone else been having this issue? There's no noticeable wear on the bolt or on the bolt lock, so I'm puzzled why it's not locking back. Quote Link to post Share on other sites
Spencerman Posted May 20, 2011 Report Share Posted May 20, 2011 The guide on page 29 is great because it shows you which way to turn the nut. Knowing that you are turning it the correct way help immensely as it is very tight indeed (mine even squished some of the metal I had to turn so hard) but a good fit with some pliers will do the job. I did at one point have a problem with my bolt not locking every time, so I stripped the lower group and lubed the spring part and catch, and worked it up and down by hand to get the lube right in there. No problem anymore. You do need to drop out the lower to get to the spring. Quote Link to post Share on other sites
mnmc10 Posted May 20, 2011 Report Share Posted May 20, 2011 the big nut has red thread lock so heat the nut with a torch just make sure you dont melt the receiver. Quote Link to post Share on other sites
bankz5152 Posted May 20, 2011 Report Share Posted May 20, 2011 Ive got a really odd problem with mine. Just got Part 91 (#66), new firing pin, new hammer set installed them properly but I no have a strange problem. Basically if I put the mag in then cock it it will not fire you'll hear the hammer go 'click' but nothing else. However if you cock the the rifle then put the mag in it works fine, also works fine when your run out of ammo and press the bolt release. Any ideas as to why this is happening? Not a massive problem just a minor hinderance id like gone. Quote Link to post Share on other sites
danielsilva Posted May 20, 2011 Report Share Posted May 20, 2011 Maybe the firing pin isn't smooth and is catching the release valve, not going to the "up position" fully when you put the mag on before cocking it ? If this was a M4 i would tell you to put the mag into the magwell with the receivers open to see if the firing pin is being fully depressed but being a G36 this isn't really possible Quote Link to post Share on other sites
mnmc10 Posted May 22, 2011 Report Share Posted May 22, 2011 the ratech firing pin is a tad longer than the stock. so cocking it first before putting in a mag might do for now until the firing pin wears a little. Quote Link to post Share on other sites
bankz5152 Posted May 22, 2011 Report Share Posted May 22, 2011 Right maybe so... Ill see in a few 1000 rounds.. Quote Link to post Share on other sites
GingaNinga Posted May 23, 2011 Report Share Posted May 23, 2011 Managed to fix the barrel wobble issue I was having with my G36C. As it turned out, the hop-up unit was the cause of the problem. The hop unit didn't fit tightly into the body, so there was play between the body and the unit. I added 2 small strips of masking tape to the outside of the hop unit, and put it all back together... No more wobble!! Quote Link to post Share on other sites
bankz5152 Posted May 23, 2011 Report Share Posted May 23, 2011 Ive come across a new problem... Ive lost semi auto!! Just fires full Problem Thread Quote Link to post Share on other sites
Atsalakotos Posted May 23, 2011 Report Share Posted May 23, 2011 Okay, I have come across a major problem. Since my magazines cleared customs last week, i decided to bring this to a game. Having fired a total 300 rounds, I insert full magazine, cock it and then CLICK! nothing happens.... I have stripped the gun down (Not the trigger box... I am new to GBBRs and too scared to do that) and nothing is broken / worn down. (From what I see...) When i pull the trigger, the hammer drops and the valve knocker extends normally. But the gun does not fire! Any ideas on how to solve this? P.S have tried all my 7 mags, so its not a mag problem...... Quote Link to post Share on other sites

P.S have tried all my 7 mags, so its not a mag problem...... try physically push the valve release does it release gas easily or not? you might over fill the mag cause the increase pressure so the pin doesnt have enough strengh to release the gas.

Thanks for the answer, I have tried with low pressure gas and half-filled magazines, it seems to me that the valve knocker barely touches the release valve. Quote Link to post Share on other sites
LordElpus Posted May 23, 2011 Report Share Posted May 23, 2011 Pretty sure this hasn't been posted yet... http://www.youtube.com/watch?v=s7djBUQQjmI Not sure about the stock yet, i think it's more a G36 full length item than anything shorter. Quote Link to post Share on other sites

Push it and see if it snaps back to position, if not you either have the firing pin base getting stuck. Quote Link to post Share on other sites
kepp Posted May 23, 2011 Report Share Posted May 23, 2011 your problem might be when the hammer falls it hits a pin which can fall out and create the problem your experiencing . it has happened to me and so far a little epoxy has solved the problem. When you take your gun down. cock the hammer back and look in front of it if you don't see a little pin that is your problem Quote Link to post Share on other sites
bankz5152 Posted May 23, 2011 Report Share Posted May 23, 2011 Same thing just happened to me try cocking it first, then mag in, cock again, should work. Still looking for a long term solution... Quote Link to post Share on other sites
Atsalakotos Posted May 23, 2011 Report Share Posted May 23, 2011 (edited) your problem might be when the hammer falls it hits a pin which can fall out and create the problem your experiencing . it has happened to me and so far a little epoxy has solved the problem. When you take your gun down. cock the hammer back and look in front of it if you don't see a little pin that is your problem Hmmm, I don't see the pin indeed. Can you tell me in detail how you solved the problem? Because I don't really get how GBBRs work yet... @Bankz I have read about your problem, Doing that does not work on my gun... And I haven't ever touched the trigger box. Its completely stock. Edited May 23, 2011 by Atsalakotos Quote Link to post Share on other sites
kepp Posted May 24, 2011 Report Share Posted May 24, 2011 if you have the pin you can simply use a glue or epoxy (in a small amount and be very careful not to glue the assembly together) the pin into the hole. i don't know the exact technical terms i might be able to take a couple pictures to help you tomorrow. if you don't the pin i unfortunately don't know where to find spares.

Atsalakotos Posted May 24, 2011 Report Share Posted May 24, 2011 Yeah thanks, that would really help. If I can't find the pin maybe I can find some sort of substitute from my parts box.... Or Ra-tech includes the part in their reinforced sets? Does anyone know? Quote Link to post Share on other sites
