Barrels on 510 and s410

[cporourke]

Hi folks.
I have an S410. I'm inheriting an S510block and trigger assembly, with a bent S510 barrel and shroud.
Will my s410 barrel fit? Or is the outer diameter different.
Cheers
Colin

yes , as long as its like for like , carbine to carbine , classic to classic but I don't think the 510 uses a classic barrel unless its FAC .

So the answer YES (unless its a classic barrel )
