I have a Form 4 pending on a 556 factory sbr. It has the folding collapsible stock and railed handguard. I want it to look a bit more like the 553. I bought a standard fixed/folder style stock but I want to change out the handguard.

Can I use the JMac adapter to install cut-down handguard from a 550? If not, is it possible to adapt 550 handguards to my rifle at all?

I guess if I can’t l, I’ll be looking for a plastic factory 556 handguard in patrol length and I’ll have a load of furniture for sale.

Thanks for any information to help me with this.
