I purchased a 24"bear creek arsenal upper and one of their lowers. Both upper and lower are forged and the upper is the rear charge with forward assist. I replaced the stock with a MFT minimalist extreme duty the grip is now an ergo deluxe and the trigger I had one laying in my shop is a rise armament. Here are some groups from just plinking to put a few rounds down the barrel to break it in and then some load development. I've tried 108 eld m 100gr hornady interlock 58gr vmax 55gr nosler bt 80gr eld vt. All of these shot well under moa. Some in the .4". The powders were h4831sc for the 108's. Staball6.5 for the 80 eld vt and cfe223 for the 55 and 58's. I knew going into buying this rifle I was shaking dice with some of the internet reviews that were out there. But this rifle shot well and has yet to have any type of malfunction.
