A beautiful gun from...
A beautiful gun from Heckler and Koch. The rifle came in perfect condition, and the prices at Bud's can't be beat. The CR comes with an 14" rail, Magpul CTR stock, extended mag release, HK polymer mag, OSS muzzle break, but no iron sights. I only have a few complaints. The HK polymer mags look nice, but seem a bit flimsy at the lips. The front end is a bit heavy, due to the heavy profile barrel. Some people might not care for the proprietary HKey rail system, same idea as keymod, but slightly different. It comes with 2 rail sections and you can purchase extras if needed. No problems to report so far, 1500+ rounds through it and no malfunctions. Absolutely love the gun and very happy with Bud's as well.
