Liberty Precision Machine Baby Bell Features The Liberty Precision Machine Baby Bell muzzle brake is CNC machined from 17-4 PH stainless steel and heat treated to an H900 condition giving it the strength and durability to handle repeated firing cycles. Its .395 inch bore is sized for 9mm or smaller projectiles making it well suited to a range of pistol caliber carbine and rifle applications. All critical alignment features are machined in a single setup which keeps port orientation consistent and eliminates the need for shims during installation. A 360 degree port orientation design further reduces concussion for the shooter and nearby range neighbors. Compatibility with common .900 by 24 silencer mounts makes the Baby Bell a practical choice for shooters who plan to run a suppressor on the same thread interface. The 13/16 inch rear hex simplifies installation and removal letting shooters swap the brake on and off without specialty tools. Finished in a black nitride coating over the stainless steel body the Baby Bell resists corrosion while keeping a low profile appearance. At only 1.3 to 1.6 ounces and a 1.1 inch overall length this compact brake adds minimal weight and length to the end of a barrel.
