I have an Armalite M4 that wasn’t getting any love so I decided to build an upper to compete in the NRA’s new Tactical(AR) class.
The specifics can be found on the web, but basically it’s a new category that shoots in High Power Rifle along with the sling shooters and F Class guys. The pertinent rules include:
1. AR type rifle using calibers from .223 through .308
2. Barrel not to exceed 20”
3. Weight not to exceed 14lbs
4. If using a scope, magnification not to exceed 15X
5. Harris or Atlas type bipod or sling. No F Class bipods or front rest. Rear support of the “field expedient” type. No eared bags.
6. Trigger weight no less than 4 1/2
7. Standard 10/20/30 round mags
All other prone, slow fire High Power rules apply, like single loading, not from the magazine.
This new class will shoot on the 600 yard service rifle target, 1 MOA X Ring, 2 MOA 10 Ring, etc, not the reduced F Class target
I wanted to try and control my costs so starting with my Armalite lower I decided to stick with .223 with a Wylde chambered Proof carbon barrel (yep, there went my “control costs” goal). To defray the cost of the barrel I used an Anderson upper and kept the Armalite BCG. I also repurposed my Atlas bipod, Stoner scope mount and a Leupold LRT 4.5-14X50 The only other purchased items were a Sampson Evolution hand guard and a Rise Armament 4.5 lb trigger. I still spent more than I had planned.
I’ve been sorting and prepping brass this weekend with the goal of doing a barrel break-in and maybe shoot some load development but time has run out.
I’ve got a plan though. I’m going to be using Lake City brass (LC14 and LC15 is what I have the most of). I sorted and processed ~400 cases so that should be enough for now.
I’m going to be trying the new Berger 85 LRHTs with VV N140 and BR4 primers. I found the distance to the lands using this bullet and will start -0.020 off.
I’ll post my progress here as I go along
Edit: typo on max scope magnification. Max is 15X
