AR-15 Completed Build

I finally got most of the parts for my AR-15 build up and got everything put together.

Here is a parts breakdown:

The first thing I want to really point out is the fit of the upper and lower. I have a Smith and Wesson MP15T AR-15 and when you grab the pistol grip, there is noticeable wobble between the upper and lower. They are just not “precision” fit. With the Coronado Arms lower and BCM upper, there is absolutely no wobble. Everything is an exact fit. I try to outline some of that in the review video at the bottom of this post.

This was my first from the ground up build, and I was surprised how easily everything went together. I’m really looking forward to getting this rifle out to the range and seeing how it shoots!

I’m waiting on getting a CA legal bullet button and then I will get to the range and a range report and video will follow. Please subscribe to my youtube channel to get updates on when I get everything put up. http://l.santsys.com/12QMPDE

Coronado Arms Lower Build

I finally got my lower parts kit for my Coronado Arms lower build out. I used a lower parts kit from PSA. The parts kit was a basic kit with a Magpul MOE stock and grip in Flat Dark Earth.

Everything went together well and looks great! Check out the video below for all of the details!

Coronado Arms Lower Receiver

I’ve been wanting to do an AR-15 build, from the ground up, for quite some time now. With the rush going on, it’s been hard to find parts, etc. But I was recently able to get my hands on a stripped lower receiver.

I picked up a Coronado Arms billet lower receiver (Model CA-15). This is my first billet receiver, my M&P15T has a forged lower, and every other AR-15 I’ve ever shot/handled has been forged. The CA-15 is made from 7075-T6 aluminium, with a black hard anodized finish. I’m excited to see how everything goes together and eventually shoots.

The overall look and feel of the lower is great. It’s light, but feels very sturdy and has extremely clean lines. Everything seems to be machined perfectly. There is no “extra” material and everything just looks precision about it.

I can’t wait to get my parts kit so I can build this thing out!



For the parts kit, I ordered a Palmetto State Armory (PSA) setup. It is a complete lower kit including a buffer tube and stock. It has a basic Magpul MOE stock, I haven’t had a lot of experience with Magpul stuff, so I’m looking forward to checking that out too. I went with PSA because it has decent reviews, it was a good price, and it was also instock. Finding parts here in California has been difficult at best.

As soon as the parts start rolling in I’ll do follow up posts on everything.

Burris AR-P.E.P.R. Mount (30mm)

Specifications

Weight: 8.7oz
Overall Length: 5.3125 in.
Ring Length: 4.125 in.
Ring Spacing: 2.1875 in.
Ring Width: 1.75 in.
Ring Length: 1 in.
Height: 1 in. (rail to bottom of ring)

General

The Burris AR-P.E.P.R mount is sturdy and well constructed. The scope rings fit together quite well and are held down by 6 screws (3 on each side of the rings). Each ring also has a small (2 notch) Picantinny rail on the top. This will allow for the attaching of additional accessories above your scope.

The 1 in height of the mount will help many standard tactical style, low magnification scopes to clear a fold down rear site. And the forward offset of the scope allows for good eye relief on most short stalk weapons.

The only gripe that I might possibly have with this mount is the “Made in China” sticker it comes with.
