Very nice and simple Remington 870 setup from RomeoPapa, he has posted photos and info on Remington 870 Forum:

Here’s my latest. Started as an 870 Tactical, model 5077. I’ve added/changed

Scattergun Tech Post and ghost rings sights (tritium front and rear)
Scattergun Tech oversized safety
Timney trigger kit (used the middle-weight spring). I know this will start a religious war, and many claim this kit isn’t worth the money, but it does make for a very nice trigger.

Non-MIM extractor

Heavy-duty carrier dog spring
Speedfeed reduced LOP stock modified with a sling stud on the side. I had this laying around, and prefer a more traditional look in stockes.

Brownell’s aluminum follower (red anodized). I used this follower because the gun came with an extended magazine, and I didn’t want to mess around with taking out the dimples. So I was limited to a dimple-compatible follower.

Changed out the magazine cap because I didn’t want one that looks like a nipple. It’s also a standard Remington part. There’s a Speedfeed wave washer underneath it.

Magpul front sling mount. I went this route because the sling plates like GG&G and Scattergun Tech that are designed to go under the magazine cap moved the front sling mount too far forward for my tastes. The Mesa Tactical equivalent is also good, but I didn’t really feel the need for a substantial clamp because of the location of the barrel support; I just needed someplace to attach a sling.

The gun came with a Speedfeed fore-end, which I haven’t changed yet. I do have a SureFire 618LM fore-end I may put on it after I get the gun broken in.
