So I came into possession of an Elzetta ZFH1500 light mount, and mounted it on the ol' B-CC. The only flashlight I had handy that fits in it is my old beat up Surefire G2 incandescent.
There's one little issue with the particular combo of the Elzetta mount and the 14.5" barrel, especially with a muzzle comp like the Dynacomp-
The bezel of the light is awful close to the blast area, and incandescent bulbs are not known for their blast resistance. Knowing this, and not really liking the G2 anyway (old tech, dim as hell (65 whole lumens) compared to new LED lights...) I figured it'd be a good chance to see what it could take.
Apparently it'll take somewhere between 40 and 60 rounds of 55 gr. Wolf FMJ before giving up the little electronic ghost. I was somewhat hopeful that it'd hold up longer than that, since the bottom of the comp is fully closed (to counter muzzle rise and cut down on dust signature) but apparently not quite enough.
