Roll pin as barrel pin? ??

. The gun would run just fine without the pin, and as long as you didn't mount it t0o far off the gas tube would still enter the upper.

A slightly canted gas tube can be a major headache tho.

Some of you guys have lower standards. That is OK. The barrel pin only locates it until torque is applied via the barrel nut. I will always prefer a solid steel pin for that function. If you are OK with something else, it sure does not harm me in any way.

Carry on... For the next post about a canted front sight/gas system. Whatever.

Well, a 9mm is not gas tube operated, and the rail indexes on the barrel but. Soooo, it seems just fine for this application. No issues still, happy to say!

Higher standards.........

Is the reloading bench 8 ft long or is it 8.0000 ft long?

Precision reloading

Canted front sights ...........

proly barrel extension needs tweaked.

Not a pin prob.

BTW tweaking bbl extension (if all movement there), if 5 degrees......less than a thousandth in headspace change.

Simple math, but I haven't eaten yet LOL (legit disclaimer)
