I took my 14.5 upper to my LGS the other day to have my BCM comp pinned to bring to length. Told him what I wanted, etc etc. I get it back and what he did was drill the barrel, time the comp, and what he called a 'cold press' with a hydraulic press the pin in. When I asked him about it vs welding it, he scoffed and said that this would be fine, the pin would have to be drilled out for it to be removed. Says that is how he has always done it and has never had an issue. Apologize for no pictures, forgot to take some before I dropped off at my dads.

Can anyone confirm if this is G2G? If need-be, I can tack it at home to get a weld on it.

Not so sure I'd want anyone putting a press to the area of my barrel that contains the crown if anywhere at all. Also an interference fit pin would exert pressure on the same area and i can't really see that being all to great an idea either. Above all the law regarding this doesn't list this as an acceptable job as far I know.

He can say all is good, but he is not the agency that will bust you for having a Short Barrel Rifle being the muzzle device is not permanently attached as defined by the BATFE. The excerpt below is from the National Firearms Act Handbook Ch. 2.

The ATF procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and measured.

That's why I really do not use local gunsmith since (at least in my area) they had no specific knowledge about pinning and welding and related law. One told me that I would go to jail if I use less than 16" barrel period. I was just speechless for his lack of knowledge.
Since then, I just send it to ADCO for any service. They are quick and reasonably priced, and mostly they are good!

Guys at my LGS tried to sell me a PSL by telling me it was used in WWII. No way in hell would I trust them to do work on anything I owned.

Where are you in OH?  If you're local, stop in and I'll zap a quick weld on the pin for free while you wait. Thats all it would take to be legal.

Yup.  That pressure makes me nervous.
