Hey all--
Bummer of an experience that I would like to share with you and maybe get some advice from you guys so it doesnt happen again:
One of my customers brought in his Remington 700 Tactical in .223 with a 20" barrel to have the barrel threaded for what I assumed was a muzzle brake.
No problem, chucked the stripped, barreled reciever in my 4 jaw and dialed it in to 0 movement of the indicator. Took the muzzle end with a gage pin in the bore and the barrel supported by the center rest approximatly 1" from the muzzle dialed in the gage pin again to 0 movement of the indicator. Double checked both indicators and all is well. Proceeded to turn down the OD and single point to 1/2 x 28 TPI. Fine.
Get a call today from the customer and he is pissed. Seems the "brake" was actually a suppressor and somewhere along the line something ran out of true with the bore enough that a couple of the baffles and the end of the can blew out from a round striking them.
Now I get to pay for a $600 suppressor and possibly the barrel (He doesnt want it any shorter and I highly doubt he wants me to correct it, let alone look at it.)
After speaking with him I cannot find where I went wrong on my work. I have gone over my procedure mentally and all seems well. I have threaded many barrels and this is the first that has given me a result like this. One thing I did consider, is the diameter of my gage pin too small to get an accurate read?
Thanks and I am open to any suggestions.
