8point I can understand where they are coming from,you can only do so much to a product.I used to own my on shop and a man brought me a a/c compressor and a accumulater and an orfice valve to put on his caprice,I have all the equiptment to drain an a/c and store and filter R-12.This was when you bought freon 12 at K-MART,in 12 oz cans.I flushed the system and put the parts on and charged the system and It cooled in the mid 40 degree on my guage,he said put more freon in ,it don't coolas well as it did before.At least 5 times I discharged his system and flushed and changed the orfice valve.Almost 1 year later he came back and I told him I could do no more with that system.The same thing browning told me.I made him a deal and browning offered no deals,I bought a compressor from GM and the system cooled like he wanted.It cost him 200.00 more but if browning offered me a deal like that I would think they were trying,but no as usual I end up with the stinky end of the stick.But I told them this would come back to haunt them,about 2 years later a rep from browning called me to ask if my problems were resolved,I told him I had to get rid of the gun and he came apart,he swore somebody was going to have to answer to this.Mabe they are better now,my friend that sent that browning highpower back several times and they called him later to ask if he was happy,he replied yes and I bought the gun from him and kept it for several yeare and traded for some thing,I don't remmember.They seem to have changed but I have limited experience since that.Drop-Shot
