A5 threaded barrel Stock or very short aftermarket

[Bennymcpenny]

A thread in the DP section says a5 threaded barrels can be tips for DP barrel backs and I wanna find out if it's true and post pics. Looking for a shorter barrel, a stock one looks like it would work great but, a lapco or cp would be sick.

Hoping for a cheapo but, a lapco big shot can have some money.

Thanks for looking
Benny
