- Stock: Magpul ACS
- Grip: Magpul MIAD
- Sling: Magpul MS2
- Magazines: Magpul PMAG
- Misc: Reused DPMS Castle Nut, Reused DPMS Buffer Spring and Carbine Buffer
Upper Receiver
Sun Devil Billet Upper Receiver w/ Forward Assist
- Barrel: Yankee Hill Mfg 16" Carbine Length, Chrome-lined 1:7 twist, 5.56 NATO, M4 feed ramps
- Muzzle Device: Primary Weapons Systems, FSC556, Flash Suppressing Compensator
- Gas Block: Daniel Defense Low Profile Gas Block
- Gas Tube: Reused Leftover from S&W M&P15ORC Piston Modification (Carbine Length Tube)

- Rail: Daniel Defense M4 Rail
- Rail Covers: Magpul XTM
- Sights: Magpul MBUS (front/rear)

- Optic: Aimpoint, CompC3, 2MOA dot
- Vertical Grip (Forward): American Defense Mfg/TangoDown, BattleGrip Auto-lock lever, Quick Detach Short Vertical Grip
NOTES
- Magpul BAD does not fit with Sun Devil upper .
- Daniel Defense Lite Rail does not fit on a Sun Devil Upper Receiver--lesson learned, so I used an M4 Rail.
- Bushmaster 2-stage comp trigger with ambidextrous safety was ill-fitting; safety selector was rough when exercised - replaced with RRA safety and Timney trigger group.
- Timney install requires pliers to move the spring arms to either side in order to reach allen head seating screws that secure the group in place--there is a trick to it.
- Definitely fun to get all the packages in the mail, but shipping costs can be a bear coming from multiple suppliers and at different times. Definitely a nice rifle despite what it cost to assemble.
- Built as a high-end lead chucking machine--works very well; extremely pleased with my rifle.
Still Considering
- Norgon Ambi-catch
- Is there a way to mount a Magpul BAD without using the backing plate?
I used this rifle at a Pat Rogers (EAG Tactical) carbine course in early October. I never fired this rifle prior to the course and it is the first I have ever built from scratch. I shot decent, but wish I had it zeroed before going to the course because I didn't feel I had the best zero the entire two days, although I shot decent enough. I definitely like the 2 MOA Aimpoint as it does not cover too much of the target. The Seekins and Sun Devil receivers fit very snug on this rifle. The Timney 3-lb trigger is very light--good for quick shots without a lot of squeeze play to prevent jerking the rifle around. The PWS FSC556 was interesting since I have only ever used a flash hider--this compensator seemed to keep me on target fairly well between shots. The Magpul MS2 sling made the weapon easy to control while I moved and manipulated the rifle for various drills. The forward grip was perfect as a reference point on the 12-inch DD M4 Rail. It was nice to watch the smoke billowing out through the holes in the rail when she got hot. Overall I am glad I built this rifle and I am very pleased with myself for building something that did not blow up in my face.
One thing I did at the course that I have never done is use Slip2000 for my lube--Slip2000 is to AR rifles what that Franks Red Hot Sauce is to food, where that old lady says, "I put that Sh!t on everything."--in this case, the bolt, charging handle, bolt carriage, and a little on the trigger group. Here are a few pics. The rifle has some scratches, scrapes, and a lot of slip2000 splatter on it in the pics. I cleaned it up after the course, but hey, I built this thing to run.

This is a pic of the BCM Gunfighter charging handle installed--too bad it was after the course finished.

A pic before firing at the course--had a Gear Sector sling on it while waiting for my Magpul MS2--the Gear Sector is home on another rifle.
