Standard Parts Bm 59 Gas Cylinder Install

As Mike Baker reported new US made gas cylinders are available from Standard Parts

I did get one of these gas cyls as my BM62 gas cyl is not tight at all ( I have peened the splines a little but without much improvement).

 

I attempted to test fit it and it is a very tight fit. So tight that is did not feel comfortable proceeding. I tapped with rubber mallet and a wood block and the resistance was so great that I got a little gunshy to go furthur. I have a replacement Beretta made BM59 cyl and that goes on very easily. I'm wondering how hard I can go to tap this on. I don't want to messup the barrel. I'm worried if I get this on the splines will be so wide the factory cyls will never fit again.

 

Thoughts?

 

 

Here are some shots of the Standard Parts gas cyl compared to a BM62 part.

The fit and finish is very nice.

I have not tried to contact him but I should. I bought it in April and have not tried since then. I will send him a note this week.

I have had numerous gas cylinders of Greg's (standard parts) in my shop for BM and Mini-G builds. I have not yet had one that didn't go on perfectly tight. Perfect means I use a cut off barrel stud, screw it into the gas cylinder, tap it on. I like it tight.
