First things first, when I ordered this I did kind of piece it together. I ordered the Spider (Bullet) Lower w/ Standard Kit - M4 Stock ($250), than a couple months later I ordered the Spikes Tactical 16" Mid-Length 5.56/.223 Upper Receiver. For sights I used the classic AR-15/M-16 carry handle for the first 6 months. I thought I had my dream rifle all set from there and had no plans on doing anything to it.
The first thing I did to it was about a 6 months or so after I bought the rifle I put the original Primary Arms Red Dot on it. This was their first run of Red Dots and it worked flawlessly. James is currently running on his AR-15 in place of his Eotech which stopped working. The next thing I did was add a Specter 3-point sling on the advice of James, since I was carrying this around the desert when I would go shooting. I would often sling the rifle while shooting the .22, incase we ran into aggressive creatures(human or nonhuman). I actually kept it that way for another year figure I was done with it and I was set on the way it was set up.
After that year something bit me and I got into a modifying mood! The first thing I did was put the Magpul MVG (Vertical Grip on it, then I got a Primary Arms Weapon light, then a Magpul MOE pistol grip. I switched out the stock to the Magpul ACS stock after James put on his rifle, I then switched out to the Magpul MOE Plus pistol grip. I switched out the Primary Arms Red Dot to the Primary Arms 2.5x Scope. I even eventually used the Primary Arms Digital Template to camouflage it. The last two things I added to the AR-15 was a Magpul MS4 Single Point Sling and a Primary Arms Reflex Red-Dot.
It is pretty crazy when I look back and see what I all did. I have so many odds and ends pieces for an AR-15 now. I think my main problem while doing this build was not having a clear vision of what I wanted it to be. I changed what I wanted to use the rifle for every couple months. This lead to buying parts here and buying parts there, so if you are going to start a build have a clear or at least a semi-clear vision of what you want to do with it. Do you want it to be a lightweight rifle, an all-around rifle, long range rifle? This would have cut down on what I bought and how many times I switched parts. Another thing to be aware of is, know what parts are needed for the type of rifle you want to build. I made the mistake of buying a Red-Dot when I wanted something longer range, I planned on making a lightweight rifle but that was all blown to hell now.
With my AR Pistol build I am putting together a clear cut plan with what I am going to do with the rifle. I strongly encourage doing that, that way you aren’t wasting money switching things out. I will keep all you readers update with the progress of my AR Pistol build. To end this all I will give you some specs on the rifle as it sits now
