It didnt blow the seals the person who put the barrel in decided not to notice that the barrel was rotated and destroyed part of the hopup rubber. The hopup used on this gun is unique it has a "U" shaped portion on the end of the barrel and another "U" shaped portion on the hopup rubber, whoever installed it pushed the barrel into the hopup so that these pieces didnt meshed and destroyed the "U" shaped portion on the hopup rubber. So all I did was rotate the hopup rubber so that this destoryed part wasn't hanging in the barrel of the gun and now it shoots pretty good. The type of gas I used had nothing to do with the problem and I am positive that green gas will work just fine with this gun being that the bolt assembly is made out of steel.

well Im almost ready to give up on it everything on the gun operates perfectly except for the hopup, I dont know what to do it just doesn't make any sense I've tried everything and the range on this gun is still pretty much like a mini electric I posted up on the trouble shooting forum so hopefully I'll get some help but I think Im ready to sell it soon  I f I cant get this problem fixed or convert it to 6mm some how I dont know.

It finally arrived yesterday, it is probably the most solid and bueatifully made gun I have ever owned, all the sites front and rear are extremely easy to adjust and everything comes swimming in oil. The bolt operation is very smooth and makes a lot of noise when cocking it. I did have some problems with it right away though which is really dissapointing, the first issue is the hop up, it is extremely sensitive and I made the stupid desicion to try to adjust it. It fired extremely well right out of the box with great range but once I adjusted the hopup the range went out the window it went from a good 60ft. to about 2ft. I tried as hard as I could to get it back to where it was but I still havn't been able to fix it. So I went a different route I had found some reviews before I bought it that had said to not listen to what the sites say and use green gas instead of hfc134a, the gun would be able to withstand more powerful gas as long as the internal screws were all extremely tight (which I ended up dealing with later today). I brought the gun down to the jungle toy in tempe and was test firing it with green gas and after a few shots the bolt slide started jumping out of the chamber. So I opened it up and tightened all the screws and it worked fine again. I eventually unscrewed all the screws that were loosening themselves and put lock tight on them and scewed them back in as hard as I could and now it works perfect, and is very loud. The upgrade to a new gas also fixed my range and now my hopup works better, its not as sensitive. I'm almost positive that nothing is going to get destroyed becuase the entire gun except for the wooden parts is made of of steel and iron, it is extremely strong and very heavy. Servicing the gun through all of this was very easy becuase the gun breaks down into three pieces, the trigger assembly pops out by pulling down on the back of the trigger guard, and the rest of the gun comes apart in two pieces by loosening one screw in the butt of the gun. The gas resevoir is also nice and big and the most clips I've shot out so far is 5 without having to fill it again. Marushin did install a bolt catch system so that the slide doesnt slam down on your thumb but it doesnt always work, I've almost caught my thumb a couple of times. I like the gun alot and once I fine tune the hopup and adjust the sites it will be a very good primary or secondary weapon becuase I still have my FAMAS. Here are some pictures.

awesome yeah i wont use this for CQB and it only shoots 270FPS unless you buy an upgrade or something i forget what site had it advertised i think it was probably redwolf. The upgrade will make it shoot 330 with hfc22.

well ill have a marushin M1 Garand probably sometime  next week or week after and ill let you all know how it is im getting it from dentrinityshop along with 4 mags and bb's but it kinda sucks dentrinity doesnt sell gas anymore or something becuase i couldnt find any on the site so im probably gunna run over to one of the JT stores and see if they got any hfc134a. From what i've read on this forum so far im guessing AA has no problem with 8mm BB's.

I have experiened no jamming at all with my 6.03 barrel and i have a FAMAS which becuase of the high rate of fire i usually use full auto, I just clean my barrel after every game to make sure its perfect so no bb's will jam. I noticed an 8-10 fps increase and an increase in distance of about 20 to maybe 30 feet depending on wind conditions. The most significant difference is probably the accuracy.
