Briley barrel bushing

Post by LenV on 6/8/2015, 1:53 pm

First topic message reminder :

Has anyone tried one of these bushings? It looks like a neat way to go for a RO. They come in drop in or gunsmith required. I might have to give one a test drive. Thanks in advance for any input.

Hi Jerry,
It shoots pretty good, but still working up loads. Only used 700x so far.
If you only angle bore your bushing to the actual barrel angle, does it need any relief areas to be scraped?
I really like all of your dedicated tooling for each operation!!!

It will go into battery, but it won't unlock..The exact angle will not work.. But, if you divide the sine bar vertical "H" by 2 and bore that angle in a back bored bushing, that leaves approx. .100 land,  it work great..and you can run a nearly metal to metal clearance.
EGW thick flange gunsmith fit are the very best bushings.
I turn the OD first

Then I take a truing skin and then back bore

Into a collet fixture mounted on another sine plate set at the calculated angle and zero is established.. 

Then bore...I love boring, it is sooo precise.. Smile

I received my Briley bushing yesterday. Being I ordered smaller ring and larger bushing so as to fit it as I like it, it didn't fit the barrel or the slide and I needed to fit it as I wanted. But I noticed the ring fits into the bushing a little loose, also moves forward and back a little. Is this normal??  I can't feel any sideways movement but will check it after installing it with a dial indicator. I have another on the way, getting it to fit a friends Gold Cup. That one should be here early next week, I'll check it. I also noticed the area in front of the lug is undercut and is quite a few thousandths less than the the diameter in back of the lug.(longest section) I got the .703" Bushing and my Slide is .701". If I recall the front of the lug is .695"
