SigTac CP1 Prismatic Optical Scope (3X)

I'd had my eye on this optic for some time now, and so when PSA dropped their price, I was eager to get a hold of one. The optic is made by ITac (apparently their products are Chinese made, and they are commonly rebranded. Sun Optics sells the exact same scope, but you save about $75 on your Sig Tax) The adjustment turrets are capped, and offer .25 MOA adjustments. The body is aluminium and is anodized black.
View from the right. Note the SigTac branding on the mount.
The integrated mount is secured to a 1913/Picatinny rail by tightening two nuts. This can be accomplished with either a wrench of the appropriate size, or a flat-headed screw-driver.
The ranging tics are intended for 5.56 x 45mm NATO M193 Spec (Federal XM193). The zero is meant to be set at 50 meters if you intend to use the ranging marks. From the 600 meter to the bottom of the thick portion of the reticle is roughly five feet and six inches at 100 yards (168cm @ 100m)
The reticle illuminated red on its lowest setting (so that my camera could capture it in all its glory).
While experimenting with the illumination, I found that none (black) was best during the daytime hours. I spend three hours peering through the glass down the street and observed that the glass is clear enough that no adverse affects were felt aside from the fagigue of holding my left eye closed for such an extended period of time.
For some reason the picture of the green illumination turned out better. Forgive the glare.
During the late evening/nightime hours (late dusk to early dawn), I found that the red reticle was the easiest to make out without obscuring the target too badly. I spent most of the time on the lowest of the five settings.The green illumination I found most useful on its highest setting when I was having trouble making out the reticle against dark backgrounds during daylight hours. This color was too overwhelming for me at night and seemed to overpower whatever I was looking at. If you look at the left of the image of the green illuminated reticle, you will notice a rather pronounced artifact. That is not a trick of the camera, and is present in both this, and the red illumination modes. The severity of the effect is directly related to the brightness of the reticle.

I noticed when looking at the reticle through the scope the wrong way (through the objective lens) that the reticle was visible while illuminated. I had intended to perform an experiment to determine how far away the was visible, but time was prohibitive these past few weeks, so I will have to get back with you in the upcoming weeks, with pictures if at all possible.

Practical technical specs are as follows.

Magnification: 3X
The red and green illumination modes feature five settings each.
The field of view is six degrees or 10.5 meters at 100 meters.
The eye relief is 14.9cm/5.9in..
The exit pupil is 1.02cm/.4in..
Parallax is set at 100m.109.36yd.
For those of you who care, the scope weights 13.9 oz.

Something interesting: The scope includes two crush washers. If anyone knows why, leave a comment.

Damage Industries M4 Buttstock w/QD Mount

This is going to be a somewhat boring post, because we all know what a typical M4 stock looks like, and we all know what a QD (quick detach) sling point is. Like any Mil-Spec stock, it fit perfectly onto my Mil-Spec receiver extension (or buffer-tube for those of you not into the know, or dislike using the real names for things). This stock, in all honesty, is nothing special.
The stock comes in Black, Flat Dark Earth, Coyote Tan (pictured against a piece of unpainted drywall in late afternoon sunlight), Foliage Green, Olive Drab, and the hilariously poop colored "SHTF Brown"
I was considering getting a Voltor EMod stock because of its utility, but when I took fifteen minutes and thought about it, I really don't need storage for six AA batteries, or a rubberized buttpad, or waterproof compartments. Though, I will be getting one later on, probably for a more rugged build, if not just as an upgrade for this rifle. The main reason behind getting this stock was just because I needed one, and I figured "eh, might as well." So here it is.

March

Good afternoon (as this is written). I apologize for those of you who have been following this blog thus far, as I have been unable to post anything regarding my build. As you are all aware (unless you are a liberal celebrity with your head so far up your [fill this in for yourself] that you are now able to see again), times are tough economically. However, I did better last month than I had anticipated, and will be posting twice this month.

I hope you enjoy what I is upcoming, and will see you later.

Damage Industries Enhanced Spring, Recoil Buffer (Carbine and Rifle)

The carbine length springs come in plastic bags that are heat-sealed at one end
I purchased these four springs from Damage Industries LLC last year (today being 1/9/2014) during one of their Deals of the Week sales. They are made from chrome-silicone and sports a black oxide finish. Each spring is estimated to last more that 750,000 rounds a piece, according to their website and a video on YouTube, titled "AR-15 Buffer Springs - More than you need to know". That's probably more than I'll ever shoot in two years (most likely held back because of a lack of money and time, not lack of desire).

The rifle-length springs a shipped using an older method: paper wrapping.
Personally I think it looks pretty sweet.
I bought these springs when I was still making up my mind about whether I was going to build a full-sized rifle or a carbine, which is why I have two rifle-length springs and two-carbine length springs. As you may have guessed from the receiver extension/buffer tube I chose, I am building a carbine. I will be doing my best to purchase a lower receiver and tools to put everything together.

PSA Premium 6 Position Mil-Spec Diameter Buffer Tube Assembly

I purchased this kit from Palmetto State Armory this past November. It is pretty straight forward as to what it includes. The actual buffer tube (receiver extension), is standard Mil-spec diameter. The buffer is standard carbine weight. The spring included is mil-spec, carbine length that I do not intend to use, opting for a spring that claims to be better than those made to military specifications (like that's hard to believe - I'll have a post on the spring I intend to use sometime later this week).
The premium buffer offered by PSA features a black anodized coating, as
opposed to the gray anodize on standard mil-spec buffers

Mil-spec (six position, carbine) receiver extension, end-plate and castle nut.
