Hello,

I am looking to give my Siamese Mauser in 45-70 a makeover.

Some things I would like to have done:

Rebarrel - Currently has a Navy Arms 17.5" barrel. I would like a barrel with a little bit more of a taper and be about 20" long.

Metal Work - No rust, but there's some pitting here and there. It needs a good blasting and a finish.

Stock - It has a straight walnut stock from Fajen. It's nice, but I would prefer a straight comb pistolgrip style stock.

Sights - It is not D&T, but I am thinking of having it D&T for a rear peep. I would like to also have a banded front sight installed.

Other than that, it feeds fine, has a Bold trigger and shoots well.

I am not upto par with doing this kind of work and would be interested in knowing of someone who could do this for me. Any help or ideas would be appreciated.

Thanks,

Matt

Okay, Don. I have to confess to Bubba style fitting. I don't have any specs. I just filed and tried till it worked and gave me proper nose protrusion. As I mentioned above, when you use the Siamese fp it gets thicker down the shaft of the nose and it becomes necessary to turn some of the side of the nose off. As it goes farther down the fp tunnel it starts to bind otherwise.

 

I never took anything off the cams, only the forward shoulder. That was stopping on whatever down in the bolt in the fp tunnel.

 

Remember, with the Siamese fp the bolt cam/gas diversion shoulder is resting on a shelf after it has been rotated, rather than down in the cam well, hence the need to shorten. That's why I said I thought the Yugo is a better way to go. The cam is where it was designed to be...I think.

 

I've done four that way, three 45-70s and one 45-90 (still a work in progress) and so far so good. Still have ten fingers and two eyeballs.

Hey Brad,

Just wanted to give you an update since it's been awhile. I haven't done too much more with it right now, as I really want to get a new stock for it. Does anyone have an idea where I could get one for this action with the fat navy arms barrel it has?

Also, what's weird is the shroud clears the safety completely, it's pretty close, but it does not touch it at all. I was racking it hard, soft safety on or off and it doesn't hit???

Thanks,

Matt

Hey guys,

Thanks for all the replies and info. The trigger arrived today and it looks great. Like you said Brad, it required a little bit of grinding to clear the trigger guard.

Now I have a new small issue that popped up. It seems in my unprofessional opinion that the sear is too tall, or something is off just a tad.

With the set screw snug on the trigger against the action, I can not get the trigger to fully "fire". It feels like the trigger only releases at about 50% and barely clicks. If I loosen the set screw to the point of the trigger housing being sloppy, I still get the wimpy click but, when I lift the bolt or take it off safety I get a normal "fire" from the trigger.

Thanks for your help,

Matt

EDIT....

It appears the sear is indeed too high. I shimmed the back end of the trigger housing and adjusted the set screw out to level it off. Cocked the bolt, took safety off, and BAM trigger seems 100% better now. Nice solid loud click. Is it common to have to shim the trigger? Are there shims specific for this I should use? I just used a small washer to test this with.

Here's how it looks:

Hey Matt,

 

I'm going hunting this afternoon so thought I better get your answer ASAP.

 

I installed a Bold on an already completely modified Siamese action and it worked perfectly, safety and all. However, as on the Timney, the front of the housing interferes with the slanted trigger guard's seating, so the front of the trigger housing must be beveled to accommodate the tg. A project that takes two minutes.

 

Good luck. Let us know how it goes.

Hi Brad,

Thank you for taking the time to answer me. I went ahead and ordered the Bold trigger from Midway!

Is it possible to leave the original shroud and safety on, and still use the Bold trigger/safety? I figured I could swing the original safety over to the "fire" position and just use the Bold's side safety as my main safety?

Thanks for you help,

Matt

Hello,

I was curious if this trigger would fit in a Siamese Mauser? I have a nice conversion that I am looking to upgrade the trigger/safety on.
