Help me build my next shotgun

[GOLDEN GUN]

Ok so another cal gunner posted his 12 gauge slug rifle and now I want one.

He built his off a Remington 870 sps super slug with 25" barrel.

I'm looking to do it similarly but with a semi auto receiver. Anyone have any guidance on this?

Like where I can find that exact same barrel and if any semi auto receivers take 870 barrels?

Any alternatives?

That is very cool. I'll be watching your progress.

I would think that a legit gun smith can fabricate and attach a barrel extension pretty much to any semi receiver you want using the choke threads. Its gonna cost you though.

Does remington make a 1100 or 11-87 version of the gun? If not unlikely your going to find the same barrel. How about a Hastings.

Here's a company that does box mag conversion kits for Mossberg 930's, Remington 1100's, and others.

A little info from Recoil.

Remington makes a semi auto slug 11-87 with a similar barrel.. It's 4" shorter not fluted, and a smaller diameter..
