Ok... The top rifle.
I started and finished that project about two years ago. I got a Spikes Tactical lower from Modern Outfitters here in Meridian. I ordered a basic build kit off of Sarco Inc. for about $370. It was nothing special. I just wanted to build one from the ground up. Me and T45-Fixer built it over the course of an afternoon. I have been tinkering with it ever since. A few weeks ago, I added a polished nickel fire control group and a nickel boron bolt carrier group. I also knocked off my front A post and installed a free floating hand guard from Monstrum Tactical. I am now happy with it as is.
My office buddies got the itch a few months ago to all build ARs... There are 8 of us. We all bought 80% lowers and had them milled and coated. I wasn't happy with mine, so I abandoned it. Sooo...
Bottom rifle... Found a place selling Anderson lowers for $48... So I grabbed one really quick. I started buying a piece here and a piece there. Got a 16" chrome lined barrel with an A post on it from GeauxArmory.com, along with a Brownells upper receiver. Bought a basic fire control group and bolt carrier group from Pallmetto St Armory. Buffer tube from Cheaper Than Dirt. Magpul grip and stock from Modern Outfitters here in Meridian... and drop in quadrail from Monstrum Tactical. Actually... After thinking about it.. I bought the nickel fire control group and nickel bolt carrier for this rifle, but ended up putting them on my first rifle then just swapping the basic parts to this one.
My observations from both projects... A kit is the way to go if you want to build it quickly and cheaply. The shopping parts is time consuming and you'll start second guessing yourself the whole way, but youll end up with a much better rifle.
My tips... GeauxArmory.com has the best looking kits at a VERY resonable price... About $375 for the .556 nato kits. They are nice people and I got my stuff quickly. Monstrum Tactical... I cant tell you how happy I am with their hand guards... The price is right.. At about $60 +/-. Service is excellent also.. and quick shipping. Brownells is the worst.. The absolute worst.
This is the top rifle after I initially built it. It has gone through quite the evolution.
