I recently decided to get a new at-15 platform rifle, I'm not a huge fan of the .223 - 5.56 round so I did a lot of research. I decided to go with the 300 blk. I reload my own ammo so cutting down .223 brass, that I probably have a few thousand pieces laying around, and resizing is no issue. I grabbed a Spikes stripped lower at Dury's Gun Shop here in San Antonio, also got a RRA national match (light) 2 stage trigger while I was there. I had a few old, semi complete, lower parts kits in the gun parts drawer so I was able to piece together the rest of the lower parts without spending any money. I always knew the gun part hoarding would pay off.
I got online and found a Spikes upper receiver and bolt carrier group for a really good deal so ordered those. Grabbed a 16" barrel, low profile gas block, gas tube, and charging handle from another online store for a pretty good deal. It took a while to decide on the hand guard, so many options out there. I like quad rails but I dont want a lot of weight hanging over the front end. I decided to get the Seekins Precision MCSR v2 key mod free float hand guard.
So at this point Lower is completed, all of the other parts show to be here tomorrow afternoon via fed ex and one box from USPS. The only thing I lack at this point is a good compensator for the end of the barrel, but that shouldn't be a problem. My goal was put together a good rifle for less than I could pick up a big name builders gun for. (+- $1,500 on the cheap end) I'm no newbie to building, I've built around 10 AR's in the last 7 or 8 years. All have been sub MOA rifles, one in the 1/2 MOA range. I was an armorer at the Sheriffs office so I did have training, not that you necessarily need it with the AR platform, its basically legos for adults.
Ill post up there pics of the upper and completed gun along with range reports for anyone interested in a 300 blk build. For now here is the lower.
