Abstract

Claims (20)

1. A flash suppressor for use with a firearm having a barrel, the flash suppressor comprising:

an elongated body with a forward portion and a rearward portion collectively defining an external periphery of the elongated body, the elongated body including a rear socket at the rearward portion configured for engagement with the barrel;

a central bore through the elongated body extending from the rearward portion to the forward portion and sized to receive a projectile fired from the barrel;

at least three slots formed radially from the central bore to the external periphery in the forward portion of the elongated body, the at least three slots including open forward ends and closed rearward ends thereby defining tines between adjacent slots;

wherein the forward portion of the elongated body portion is tapered such that an outer diameter of the elongated body portion decreases along the entire length of the tines from the closed rearward ends toward the open forward ends; and

each slot having a transition portion extending from the central bore to the rearward end of each slot, wherein each of the transition portions is angled forwardly and defines a concave bottom profile.

2. The flash suppressor of claim 1 , wherein the central bore defines a longitudinal axis of the elongated body and the transition portions are angled at about 45 degrees from the longitudinal axis.

3. The flash suppressor of claim 1 , wherein the taper of the tines is angled inwardly at about 1 degree.

4. The flash suppressor of claim 1 , wherein the tines include a longitudinal groove formed in the external periphery and wherein the groove extends along more than half the length of the tines.

5. The flash suppressor of claim 1 , wherein the rear portion of the body defines a bearing surface along the external periphery, the bearing surface including an acme thread and an annular shoulder for direct coupling with a sound suppressor.

6. The flash suppressor of claim 5 , wherein the acme thread includes a single lead.

7. The flash suppressor of claim 1 , wherein the at least three slots consist of exactly three slots.

8. The flash suppressor of claim 1 , wherein the rear socket includes internal threads for connection with the barrel and external flattened walls configured to engage with a wrench.

9. A flash suppressor for use with a firearm having a rifled barrel, the flash suppressor comprising:

an elongated body having a forward portion and a rearward portion, the rearward portion configured for engagement with the rifled barrel;

a central bore through the elongated body extending from the rearward portion to the forward portion, the central bore configured to allow a projectile fired from the rifled barrel to travel therethrough;

three slots formed radially from the central bore to an external periphery in the forward portion of the elongated body, the three slots including open forward ends and closed rearward ends thereby defining tines between adjacent slots; and

wherein the forward portion of the elongated body portion is tapered such that an outer diameter of the elongated body portion decreases along the entire length of the tines from the closed rearward ends toward the open forward ends.

10. The flash suppressor of claim 9 , wherein the rear portion of the body includes annular threads, wherein the threads have an outer diameter that is greater than an outer diameter of any other portion of the elongated body positioned forward of the threads.

11. The flash suppressor of claim 9 , wherein the rear portion of the elongated body includes an annular shoulder for direct coupling with a sound suppressor, wherein the annular shoulder includes a plurality of angled teeth thereon.
