I had a problem with my M11A1 today (old version). In my attempt to rectify the problem, I accidentally damaged the internal bolt system beyond repair.
If you can see that bolt (or piston, whatever) you can see that there is nothing sticking out of it. There is supposed to be a smaller diameter tube sticking out which controls the blow back feature and firing the BBs.
I ordered this part:
But, I have a concern: Does that part come with that internal valve system pre-assembled? Or do I need to order something more and put it together?
Thanks for your replies.
***On a different note, I was cheated into owning this gun. I bought (from ebay) an m11a1 that was advertised as being a used NS2. I knew as soon as I got it that I had been cheated, it was obviously the older version. Today was my first time using the gun, and it was having problems with blowing back into a cocked position, so I started investigating the internals.
I noticed that the bolt on this gun has to be seated properly within this:
AND REMAIN FULLY SEATED, or else it looks like the gas would not be able to travel down the barrel, only get wasted. However, in my gun the external cylinder was slipping forward on the bolt, causing it to misfire and preventing blowback.
What seemed strange to me was that once I had this taken apart, it looked like the external cylinder MAY have been designed to travel over the bolt (for what reason I don't know). I decided that the travel of the external cylinder over the bolt was a bad thing, and tried to fuse the two together permanently.
Unfortunately, I botched the job and ended up worse than I started. If you're still with me at this point, should the external cylinder be free to travel up and down the bolt randomly?
Thanks again to anyone willing to help me. I love this gun. So much that I think I will buy the NS2 version as well.
