Help me understand why......

Thanks for your honesty, and you are exactly right about the Chinese rc stuff, most everything I have is powered by Castle mambas, Novak, Trinity or spec'd stock in the slash, I do however have Flysky Gt3b Chinese radios which are very good and in one crawler there is a C spd control, which is great for just playing, but I do understand what your saying, and I'll get em sorted out and pass them on to my kids when I upgrade to something decent, then trick it out like I do everything else, but I'm done polishing turds....

I, and the guys I shoot with, must be extremely lucky.  There are about 15 different "Chinese" guns represented in our 'shooting group' and all of them perform very well.

Well, You fellas are sure luckier than I am, Just noticed today that my barrel is bent down....Not barrel droop....Bent....i believe it's happened a little bit at a time as I was cocking it, because I had to keep raising my crosshairs on the scope.....

Since you never wanna state which rifle you are specifically talking about, I'll make a simple engineering statement.  The Chinese engineers are very proficient, at "reverse engineering" a sample that the receive.   Pretty Thorough.
You would really have to try...to pemanantly bend a new steel barrel, in even a 35-40# cocking effort...unless you just laid on it, after it was properly cocked.  Doing that overpowering of the leverage, would also stress the barrel attachment, the pivot bolt/breech assy,  and could also change your lockup...and problems with consistency.
Like the other guys say...  Why buy cheap guns and then complain?  Especially after doing homework?    Tell us which specific rifle you are having problems with.    There's lotsa good experienced guys here, that can help.  Just gotta let them know the rifle....    I know they'll help you find where the problem lies.  Good Folks!
Again.  50-70yds from a cheap Chicom B/barrel rifle is a real stretched and unrealistic expectation.
Heck....  IF that was true...we'd ALL have them!
