Visual inspection...
Visual inspection revealed no flaws. Workmanship is superior. Installed without any issue. Has cycled perfectly for several hundred rounds. Have yet to have an issue with the many Spike products I have purchased over the years.

Just had this bcg...
Just had this bcg installed by my local armorer. Bcg does not extract the round.. (round will not catch in the lip of the bcg to be grabbed for ejection). Bcg was worked on for a little over an hour woth every part switched out, upgraded, no reseult, then restored to original.. End result gun will fire, once.. then round must be manually extracted, due to bcg failure. Will be contacting the manufacturer for a replacement of equal or greater value due to money I have put in to correct their mistakes.. Other than this issue bcg seems to be quality made and very sturdy. Little disappointed with overall operational status and quality of item. Expected better from spikes. Hope this is just a fluke! I would recommend this product (in 100% working conditiitems. As always buds has great shipping and fantastic prices. Thanks guys. (This review in anyway, does not negatively reflect Buds Gun Shop in any way..) Purely a manufacturer review.
