2 new barrels



Log in to see fewer ads
Got two new barrels in the mail today.

A 4 inch Buckmark Challenge barrel and it came with the stock sight-- weight is 7.51oz. and the front sight is .550 tall. Just ordered a .520 tall fiber optic sight from Dawson for it (the tallest they have for Buckmarks)
This short barrel is going to go on a 2009 Camper URX with the Buckmark rifle grips on it. On this pistol I already had changed the slide, trigger and put a TK Halo Gear box on it. 2-3/4lbs. trigger pull.

And I got the 7.25 Contour Lite barrel, rail and rear sight, already had a fiber optic front sight from EWK.
This barrel is 7.94 oz. Might keep this setup, or use it later on.

Check out the thread Challenge barrel- stock sight to fiber optic sight.
I hope to take it to the range in a few days to try it out.

dimeman, when you're measuring front sight height, exactly what / how are you measuring? Height of the part when detached? Height from barrel to top of front sight post? Other?

If you're measuring from the top of the barrel to the top of the post, what are you using to measure it? The depth gauge on calipers?

Thanks,
Dave

For those last two (the fiber optic ones), you could probably measure that when it's installed, using the depth gauge (the little rod that sticks out of the bottom) of your digital caliber.

But for the top one, where the high point is in the middle, it seems like it would be difficult to measure that distance when it's installed.

Any thoughts or suggestions on how to take that measurement on a sight like that, when it's installed?

Thanks,
Dave

On the sights mounted on the barrel here are some measurements;
stock off barrel ------------------------ on barrel caliper measures
.365 BM fiber optic sight height---------------.340
.420 Browning Hi-Vis height-------------------.430
.365 Dawson fiber optic height----------------.370
.520 Dawson fiber optic height----------------.500

Since I have changed all mine from the stock screw on blade type sight to fiber optic, I guess on the stock sight you could try and measure it where the sight high point is, on the side of the sight. It might measure a little bit more since you are not on the top of the barrel.
