Hi everyone,

New here. I am planning my first ever AR15 build, and was hoping that someone might take a look at my parts list and see if I am missing anything. I am looking for a light AR to carry around some private land which has wild pigs on it. The rifle would be primarily for personal safety, or impromptu short distance predator control when walking around the land. I anticipate carrying this rifle for quite a distance at times, and would like the lightest I can get that stays near my budget of about $600.  

Is this crazy to try to build a “lightweight” AR at this price? I am not looking for any superior accuracy or a range gun. It should not see a lot of rounds either. Parts below were chosen based on front-end weight reduction being my primary focus, as well as cost. I will likely mount a cheap red dot on it only. No need for other accessories other than a 2-point sling. If you see something missing or that does not make sense on the parts selection, or improvements that could be made, please let me know.  

Parts list:
Complete Lower: PSA Stealth AR-15 Complete Lower Magpul MOE Edition $139
Upper: Anderson AR-15 Upper Receiver Lightweight Upper - SLICK SIDE $55
Barrel: BKF AR15 16? 5.56 NATO Pencil Profile (.625) Mid Length 4150 Standard Barrel $82
Gas Block + Tube: AR 15 Discounts, Assembled Nitride Low Profile Gas Block + Melonite Gas Tube $32
BCG: AR 15 Discounts, Toolcraft Logo'd Carpenter 158 Nitride Full-Auto BCG $90
Charging Handle: PSA AR-15 Charging Handle 7075 T6 Forged Mil-Spec - 24080 $20
Hand Guard: ohhunt® AR-15 Lightweight Free Float M-LOK Handguard 10” With Barrel Nut $39
Flash Hider: NBS A2 Flash Hider 1/2x28 - 1290 $10

TOTAL (Without tax or shipping): $467 Est weight: 5.6lbs

Add a cheap red dot and some tools, and I am very near $600. So again, does this look like a reasonable plan and parts list? Or will I have a piece of junk gun that doesn’t cycle correctly?

Thanks!

If that lower comes with a standard carbine buffer and spring, that all looks like it should run just fine.

Palmetto has some redo dots on sale, some sub 100$.

Thank you both. I ordered the BCG, charging handle, gas block and tube, and ended up getting the Vortex SPARC AR 2 at PSA. Now waiting for the lower to go back on sale. Will be ordering the rest of the list soon also.
