I always gauge quality of a firearm off of well..quality of a firearm, for example to me, BCM is second to none in the ar world. My Springfield 1911 has proven awesome so far for I have reached the 700 round mark as of today, (yes that is about 500 rounds down the pipe today). Very happy with it...still am going to replace the extractor or at least see if it works well so I have a spare and also swapping out the stock recoil spring for a wolff 16 lb spring (chrom silic. I think).
