I got my stamp back quicker than I expected on my 870P SBS.  The receiver is being engraved now and I'm about to have my local gunsmith/machinist cut down the barrel to 12.5" and have it threaded.

This is an 870P from Summit.  I have already put Magpul furniture on it, but need some help with what else I need.  I also have a Salvo for it.

Since I'm taking off the extension tube that is on it, I guess I'll need to get a new spring, correct?  It has an orange plastic follower... is it gtg?

What about sights?  What do you guys recommend?  I saw one that looked like had a rail on top of the receiver, but couldn't tell what kind of sight it had.

Anything else you guys recommend?

I have a similar setup.  I had rifle sights installed on my barrel by Guncat.  I'm not opposed to ghost rings sights but I've seen a few too many which weren't installed TDC on the receiver and didn't want to risk an NFA gun.  You'll want a standard magazine spring.  I don't care for the plastic followers, it seems they all eventually start getting gunk jammed into the polymer and stop running smoothly.  Vang Comp makes a nice stainless follower as does GG&G, I've got the GG&G in mine.

I installed a Surefire M300 in a Unity Tactical Fusion mount to keep it nice and tight to the forearm, it works well.

Summit is great, did something similar as well. I did get a fresh spring and a new follower, and added the Vang Comp safety. It's big and easy to disengage.

Thanks guys!  Mine has the rifle sights on it now, so I guess he could move them back when he cuts the barrel.  I'm used to just using a bead, so I'm not really sure what sights work well on a setup like this.  I was looking at the Vang Comp Ghost ring sights, but I really don't know what works well and what doesn't.

I'll look at a stainless follower... thanks for the advice.  I really like how compact your M300 looks on yours.

My Magpul furniture kinda stands out.  I was going to do FDE, but found a blaze orange set and decided to give it a try.  It's kinda starting to grow on me

Can't wait until my Salvo gets in and I can try it out.

Vang comp makes a great set of tritium ghost ring sights that also have a section of rail on top. We have had them on our shotguns (25 of them) for 6 years. No problems at all.
