Superior Arms S-15 Flattop M4

AR/M4 Custom Build Forum
1

This is my first AR build and as such I purchased a complete upper (minus sights and handguard) but the lower was built by myself. I wanted a lightweight all purpose AR that could do anything I want it to do. Originally I was going to just buy one that would work, but the more I looked the more I knew I would change. So I started from the ground up and decided on MagPul for the furniture, looks great and is sturdy.

I have never owned or even shot an AR before so I depended a lot on the online forums for information. I decided to build one to have an all purpose rifle that was easy to personalize and configure to my needs. First I had a magnified scope and later decided that I wanted an Aimpoint so I got the Pro model.

I was really happy when I was offered the 14.5" Chrome Lined 1:7 twist barrel, I really like how compact it is. I started the build in December and just got my upper this morning to complete the build. I have yet to get out to the range due to the weather. Hoping to get out next Tuesday weather permitting.

Specs for the build:

Lower - Superior Arms Stripped S-15 with a Stag Lower Parts Kit, MagPul CTR-M Stock, MagPul MOE+ AR15/M16 Grip and MagPul MOE Trigger Guard, BCM Buffer Tube and MagPul B.A.D. Lever.

Upper - Superior Arms Complete Upper Flat-Top M4 14.5" with chrome lining with a MagPul MOE Hand Guard. I believe the flash hider is a Yankee Hills Phantom but not sure (if anyone knows let me know).

Optics - AimPoint Pro with factory mount.

Let me know what you think of where I mounted the Aimpoint (as forward as I could), I had difficultly in deciding since it really doesn’t say in the instructions. Seems to work fine where it is though.

Looks great! I think your mounting point for the optic is fine, especially if you ever plan to use a magnifier with it.

No back up sights?
Stake the castle nut?
The lower looks good, the upper is suspect. I equate railed gasblocks to the likes of dpms etc. just not a fan, but that’s me.

No back up sights yet, planning on getting some folding ones from Troy Industries, unless you guys have other recommendations.

Castle nut is staked.

I was unable to get a folding front sight directly from them so I had them but on a railed gas block so I can add a folding sight, most likely this one: http://troyind.com/%20/back-up-iron-sights/folding/front-folding-black-fde/troy-battlesight-front-gas-block-mounting-m4

And then this one for the rear: http://troyind.com/%20/back-up-iron-sights/folding/rear-folding-black-fde/troy-battlesight-rear-di-optic-aperture-doa-folding

I did move the Aimpoint where the base lined up with the ejection port, I think it looks nicer. I don’t plan on using a magnifier on it, but who knows.

After you shoot it just check in inside of the upper receiver, I have one of their rifles and the finish came off exposing bare aluminum. I contacted the company and they took care of it and the customer service was quick and I had my upper back in about a week.

Mine is a complete build from them, it has served its purpose as a trainer rifle.

Hope everything works well, have fun and put some rounds through it.

I am glad to hear about the good experience with them, mine has been good despite the wait time. Which I really cannot blame them since they are overwhelmed with orders much like every other AR manufacture.

I would of done a complete build except for the fact that I didn’t want a a stock AR and then spend more money to make it the way I wanted it. Thats the only reason that I went the route I did.

I definitely cannot wait to get some rounds down range, hopefully tomorrow or Tuesday.
