Piston gas system cleaner

[survivalshop]

   I got a call last week from a friend that I helped put together a rifle for . He bought a complete LWRC 5.56 upper & I got a new LWRC lower from another friend , just so it would be a complete LWRC ( so to speak ) He was all giddy about the Piston set up & how great they are , not getting dirty & running cooler .

  Rifle shot great & I personally put it through its break in , with my procedure & if you have read of what I do to a new built rifle , even though the Upper was factory built , I punish them right out of the box , so to speak & rifle functioned fine , passed with flying colors & I was impressed with the feel & damn thing shot really good .

 

   Back to the call , he said he went to the range with his son to shoot & the rifle would not chamber a round , so is how I got the call . First thing I asked is , did you clean the rifle , yes was the answer . I said clean it again & pay particular attention to the Chamber & locking lug area, might have a piece of brass /copper to bind it up .

  He sent me photo's of before & after he cleaned that area up & now the rifle functions normally ( I'm shooting it this weekend ) The rifle has about 300 rounds through it , all Fed 5.56 , not completely broken in by my standards , but should not of had a problem.

 

  I guess the moral of this story is , no matter what they say Piston vs DI gas system , a little dirt can still stop them from working . No matter who makes them .
