School me on 1903a4s

Sev89 · Nov 16, 2014

As previously mentioned in the PGS thread I started, I won't be able to build a 1911 as my second project in 4th. There was a vendor at a gun show with a couple of stripped down Remington '03a3 receivers, so I decided to pick one up. With regards to the guidelines for our projects in 4th, we have to have something to get a drill and tap grade with (most of the instructors have a great hatred for anything and everything regarding mosins, so they're not an option). Since my options are somewhat limited, I've decided that I'd like to make an '03a4 out of my Remington action. The biggest problem so far has been tracking down the mount and rings for the scope. Does anyone know where I can find them? Is there anything else I need to look out for in this soon-to-be endeavor?

Have some pictures of what I've got so far!

Best bet? get the combination package from the cmp when they have it available or go to Old western scrounger/gibbs.

The mounts are not perfect but they work. You could also hunt down an OLD redfield base (not the new ones, the new ones are the "imperfect" ones)

Just scooped up an old mount off ebay, now I just need the rings

What makes the new ones "imperfect"?

The usgi 03a3 scope mount (base) is offset. The rear of the scope base is not centered on the receiver.

The original rear sight base does not go all the way across the receiver- if you look at the last picture you can see where they milled off part of it to make room for the cutoff. Early production receivers had a full width rear sight base but this took extra cuts and a tool change that were eliminated to reduce production costs..

Apparently the chinese engineers thought that the one they were reverse engineering was bent so they straightened it out.

speaking of bending....are you going to do the bolt handle yourself?

Yeah, I'll more than likely be doing that. There's no way I could pony up the kinda money I've seen people asking for what are supposedly original '03a4 bolts...hell, I've even seen people asking a lot for repros.

This 1903A4 will motivate you. Good luck with your project.

Get a Minelli C stock. They are really well made and are basically a drop in fit.

notice the mix of blued and parked parts in the photo. That's what you are looking for in a factory finish.

All parked would be correct for a gun that has been ovehauled.

I actually got all the parts for the action from them. They had the scope and mounting hardware as a package deal listed as AVAILABLE, I went ahead and ordered it back on the third, only to discover they removed that option (as well as the scope was being sold as a stand-alone item as well) altogether from their site day or so after I placed my order. An email and quick phone call later (last monday) and it turns out they didn't have the scope and stuff in stock anymore. I won't go into details over it, but the long story short, I sent an email yesterday asking to cancel that order. I went ahead and tracked down an original redfield base as well as original rings. Now alls I need is the scope.

I'll keep that in mind. Given that this will be one of my projects in 4th, I'll be making a stock for it. I'll have it looking the part sometime down the road

This one wouldn't happen to be yours would it?

Yes it is.

The mount and rings arrive at school today, now I just need a scope and barrel

stu929 · Nov 19, 2014

Cmp for a criterion barrel.

Champions choice for the scope maybe. Id also check ebay.

Figure I'll go ahead and ask, but does anyone here have any experience (or know of anyone) when it comes to bending '03 bolt handles?

Drmsparks · Nov 20, 2014

Not a clue but I need some done and polished if you get good at it.

Weren't the original ones cut and the handles welded back on upside down?
