I called on Monday about my Bull 20. Left a message and havent heard anything as of yet. My rilfe is only 2 months old tops and has only been to the range twice with maybe 300rnds total shot through it. It is short stroking on me. There seems to be gas comming out of the gas block (carbon build up on barrel in front of gas block). I would like to have this problem fixed ASAP. Please email me at firstname.lastname@example.org or send a message through thisd site.
