Colt bcg for ultimate build!
Fast shipping for free-99, my favorite price! Bcg came well protected and wrapped. Small scratch in on the non dust cover side, looks like from testing or something. No biggie, she’ll still run like a champ. No colt markings but mmpi tested, staked, yatta yatta. Nice tight tolerances, will last my lifetime. Great price for a great product.
