Brass Magazine Screw Cap

I always have had this on my 1873 rifles.
They mostly just look really neat and make your rifle easy to recognize.

The Springe holder stem is really helpful for assembly.

This is a quality product.
Very pretty

Replaced the stock blued one with this one on a yellow boy rifle. Looks great.
Magazine cap

Very nicely made. Fit perfect to my Uberti 73 rifle. I recommend this cap as replace, for the 66 and 73.
Brass cap
Greg Nelson - 03/03/2025
What can I say. It was a chunk of brass and it was threaded properly and it fitted right in. Although I may put a small drop of blue on it. It did start to get a little loose with use. At least I didn't launch my spring and follower down range.
Nice Touch

I wanted this just for a final touch on my uberti 1866 yellow boy. Arrived undamaged and adds that touch of brass to the rifle.
Nice Product

Purchased these to 'gussy-up' a '66 & '73. Like the way they center the magazine spring. Recommend using a little grease or lubricant before installing.
Great replacement

Nice touch
