Spetnaz Soldier 47 Posted January 10, 2013 Report Share Posted January 10, 2013 Hey guys so i got the ak-47 vented gas tube i was talking about earlier in the week. i filed in the correct spot (top side of the locking side) and it fits solid without the tension ring that was on the saiga tube. I took the ring off and tried it anyway on the ak-47 tube and it makes no difference so i just left it off. Is it snug without the ring because the ak-47 tube is snugger than the 74 style tubes?

timy 1,185 Posted January 11, 2013 Report Share Posted January 11, 2013 (edited) I'll hazard a guess. Manufacturing tolerances are a crap shoot so you never know what will work best unless you try it. On average, it could well be that 47s fit snugger than 74s. BTW, I could be wrong, but I'm under the impression that a looser tube will lead to a more accurate firearm, especially as it heats up. A little play in it will allow expansion without it pushing down on the barrel. A sort of "semi floating tube" if you will. The front floats a bit, so why not the back? It's just a guide anyway.

Spetnaz Soldier 47 Posted January 11, 2013 Author Report Share Posted January 11, 2013 no its an tight fit all around without the tension spring. what should i do make it a looser fit? Quote Link to post Share on other sites
BigChongus 765 Posted January 11, 2013 Report Share Posted January 11, 2013 (edited) I've done enough reading to convince me that a too-loose tube will affect the accuracy just as much as an overly tight one would. If it's just snug, don't worry about it. IMO it should drop into place without much (or any) persuation, but it shouldn't be rattling once locked. Not to mention a loose-fitting gas tube is freaking annoying. Edited January 11, 2013 by W8lifter Quote Link to post Share on other sites

I do think the tension ring spring thing is there so the tube won't be too tight but still won't rattle though. 1 Quote Link to post Share on other sites
Spetnaz Soldier 47 Posted January 11, 2013 Author Report Share Posted January 11, 2013 ok well its solid without the spring and from what i read is that the ak-47 tube didnt really have a spring they were custom fit to each ak but the 74 tubes just had the spring cause they were better for mass production and didnt need any custom fitting. my concern is that there really isnt any free play and im wondering if that will be a problem. i shaved off just enough material to get it to fit so its pretty snug.

rnemhrd 165 Posted January 11, 2013 Report Share Posted January 11, 2013 My tube dropped in snug without the spring. No movement. I just had to file the top so the retainer would lock. My Saiga tube fits tight as hell. Just my experience. Quote Link to post Share on other sites
