SBI ST-22 and C-71 Build Checklist - Start Here To Build Your Rifle

[SpectreBallistics]

We constantly get emails with people asking what's needed to build their own ST-22 and C-71 rifle. Here's a handy checklist with all the parts you'll need:

So essentially the only difference between the ST-22 and the C-71 is the receiver?

And the need for a charging handle/guide rod assembly for the C-71 when assembling it where the ST-22 has the charging handle built in.

I haven't seen the interior of the ST-22 receiver though, is there a guide rod and spring that's already installed aswell?

Desperate for a bolt. Always out of stock.

Yes, the receivers are very different.

The ST-22 comes with a complete charging handle assembly.

Yes, the receivers are very different.

How are they ‘very’ different? One comes with the charging handle and the other doesn’t? Am I missing something?

One has the charging handle at the side like a typical 10/22 and the other has the charging handle at the back like in the picture above at the start of the thread.

The ST-22 uses a T style ambi charging handle. The C-71 uses a regular 10/22 style charging handle.

Does SBI have any ETA on when you will have more bolts in stock? It doesn't matter if we go ST-22 or C-71, neither will fire without a bolt.

Few weeks. Our receivers are also compatible with Ruger, Faxon, Kidd, and Volquartsen bolts.

If you're talking about a completely assembled ST-22 rifle vs a complete C-71 rifle than yes essentially the receiver is the only difference if you put it together with the same parts but again the C-71 would require a charging handle assembly and the ST-22 has it built in.

I'm planning a G3 / C-71 build and am having difficulty figuring out how much the receiver/chassis adds to the OAL. I'm going to be using a 16.1" barrel so I suspect a folding stock might not be an option...

You'll need a non-folding stock or compensator to meet OAL requirements most likely.

Go 12.5" and non-folding.

When are the 12.5's shipping? Are there specific days that mag dump ships?

 

[SpectreBallistics]

We ship 6 days a week, but we primarily focus on running our CNC machines so sometimes things take some time to ship.
