After combing the WEB for hard to get information on the C-15, I was finally able to locate an evaluation from the January 2003 issue of S.W.A.T. magazine. In short their review was quite favorable with perfect functioning (300 rounds) and excellent accuracy at 100 yards with S&B 55 grain FMJ, 1.25 inches. These rifles are former Colt A2's obtained in excellent condition from South America. The Colt lowers (full-auto configuration)were replaced with forged DPMS receivers (about 3000 were ordered) and new A2 barrels were installed along with used stock sets as needed. Fit and finish on mine is excellent as was the SWAT test piece. I have yet to test fire my C-15 but since its 90% Colt, I don't expect any problems. The C-15 might be a diamond in the rough, a poor man's Colt A2. I remember about a year ago seeing ads about the C-15 and IIRC, SOG had them for sale ($600?). Its unusual that there is so little info on this gun after such a brief time off the market, even Century Arm's web site doesn't mention them and AR15.com had only two comments about it and only one of those was from an owner!
