I bought one of these "Bargin Bin" AR-15's from CMMG, http://cmmginc.secure-mall.com/shop/?cart=1988048&cat=1& , I normally would build one if I wanted one but for $625 shipped I didnt think I could all the parts together for it and thats what this is a parts gun.
Its a basic M4 style carbine, with a 6 position stock, 16" barrel, flat top. I purchased a Matech Back up rear sight for it, which I got for 1/4 of the price of a new one. My dad found me a CAA buttstock, he has one and said I need to get one I would really like it (which I do), purchased that new from a guy on AR15.com, little over 1/2 price. I looked around and found a set of quad rails that replace standard handgaurds on gunbroker, I bid low and won them for 1/4 of the price of new, these are CAA also and aluminum, should be here tomorrow. While on misson at the hardware store for the girlfriend I looked at flashlights and found an LED light that looked like it had a 1" tube for $8, bought it thinking if it didnt have a 1" tube I would leave it in my truck, got home measured it with my digital calipers right at 1", that will work perfectly to mount on the quad rail in a regular set of scope rings I can get at Walmart. I have a JP Enterprize spring kit coming to lighten the trigger up a bit, claims to take them down to 4.5 pounds, it was cheap enough from Brownells and I needed to order some small parts for the 1911 anyways.

The Matech sight instructions say to zero it at 25 yards while the sight is set on 300 yards by adjusting the front post up or down you bring your point of impact to where it needs to be than use the windage knob to get zeroed perfectly, than you are "ready" for 200-600 yards depending on where you set the sight. These arent match grade sights but they are nice, effective, and compact. They fold down give plenty of clearance for optics...which will come later this if going to be used as one of my coyote hunting rifles.

Now a cool looking rifle is about useless if you cant hit anything with it. For only iron sights mounted on it right now it does alright. The go to load for our 223 has always been 25gr of H335 with any .224 55gr bullet you can stuff in the case. Well after moving 3/4 of the way across the country it turns out I dont have any H335, I was going to buy some but looking at a loading book showed H322 suitable for 223's with 55gr bullets, I have H322 because I burn it in my 450 Marlin and 6.8 SPC. Max load is 23.0gr, so I started at 22.5 with a 55gr V-Max, which ran good and grouped decent, bumped it up to 23.0gr with the same bullet CCI 400 primers and Lake City range pick up brass....still fine tuning the sight.

I have about 100 round down the tube now about half have been V-max bullets the others were 55gr FMJ's from Armscorp, which ran and grouped every bit as good as my handloads and they are only $20 a box of 50.
I like the little carbine, I think it was a good buy....best part is the local police use Lake City ammo and never clean up there range so I have a pretty good sorce of 223/556 brass.
I have a 5-15x Bushnell with milldots mounted on my 22 hornet, which I am going to mount on this carbine, hopefully I will trade/sell the spare stocks and get a one piece scope mount for it.
