Sig 220 or 220R difference?

[akirpal78]

What's the difference between the two.

[MrExel17]

I might be wrong but 220 has no rail and 220R - "R" is considered railed maybe with a few other options like sights, grips,etc...Calguns correct me if I'm wrong.

The basic difference is the rail on the R model...depending on the age of the 220

Depending on the age of the 220, you'll have a folded carbon slide with the pinned in breach block and the flat machined into the top ahead of the ejection port.

Depending on the age of the 220R, you could have an internal or external extractor
