T-MONEY

I was so hyped up by all the crap about this awesome gun the saiga 12" oooohhhhh! Let me tell ya" i ordered one "nib frow a gun range in dallas tx. Wont say which one as not to ruin their good name..... Anyway, my saiga was beautiful! I entered the range with a box of 00 buck shot and really enjoyed almost having my shoulder knocked off due to lack of pistol grip, anyway, very nice weapon however when I pulled back the bolt and engaged thew bolt hold open lever, it literally fell out of place like a poorly constructed toy! After giving jammed and broken shotgun to the in-house gunsmith, he returned the weapon to me completely useless. The saiga 12 never left the gun range/store! So much for greatest weapon of all time crap! Sabotage? Bad luck? Am i the only one feel like this weapon is highly overated or do i need to purchase another? Im seriously considering purchasing an m4. Are they legal? Are they class 3? Anyone?
