    Was building a AR9 Pistol and was looking for something that was affordable and the right length for the build and my intentions. I was worried this barrel would be too short or too long for the 4" handguards I had already, but decided to give it a shot. This barrel mated with the Mini flash can KAK offers is the perfect fit. With the mini flashcan, the tip protrudes out of the 4" handguard 1/4-1/2 an inch and looks perfect. Thanks KAK!!
