Older barrels identification please.

[scottieb]

I've these three barrels and am unsure what marker they fit. Two are the same, minus the porting on one of them, and they've no threads at all. The third has a lot of material to it, like a bull barrel. Any help would be appreciated. Thank you.

The longer is stingray.

The other two look like sl68 stock barrels

The two shorter one look indeed for SL68 barrel but never seen a stock one with porting like the one on the right

Yeah the slots on the long barrel are for the retaining pins on a BE Stingray

[scottieb]

Well thank you gentlemen.

The porting on the one SL68 barrel looks home made. A decent go of it, but with a good eye you can tell it's not factory.

If anyone is needing one of them, they'll be up for sale soon.

Hey Scottieb, is this the stingray barrel you sold me?
