I also bought a few bca uppers in the past and just recently.. First was a 16" 450 bushmaster, wanted to try it on deer and for 200 bucks it was great. After time it had extraction issues due to a bad extractor, no biggie and a cheap $20 fix and it did shoot sub moa from day one. Sold it 2 months ago and gambled again on a new 18" upper with mid length gas system shipped to my door for $235. First 3 shots the gas tube roll pin let go but just a $1 part and fixed. This one shoots great! Im getting 1/2" ragged hole 3 shot groups @100y, I really dont care what a 5 shot group will do because this is a dedicated hunting upper but I would bet my paycheck on it that it will do just fine. Bca may not be the Lamborghini of uppers but for someone who wants to test the waters on a new caliber or just simply cant Afford a Lamborghini then this is the answer. Bca barrels are a gamble in 6.5 grendel but im 2 for 2 with the 450. I also know 5 other people who are running the same bca 450 uppers and they shoot sub moa too.
