That has not been my experience with any of my GENII NV gear and NV lasers, as the autogating shuts down the scope momentarily and the bright flash is a whiteout, so no way to attempt a second shot, this is on both 5.56mm and 7.62mm with 10.5", 11.5", 12.5", 16", and 18" barrels. The only rifle I use that does not affect the NV gear at night is my .22 long rifle Ruger 10-22 with a muzzle flash suppressor.
Of course, the size of the flash is strictly dependent on the type of gunpowders you are using, the calibers of your rifles, and the length of your barrels on your rifles, none of which were stated in the OPs original post. You can mute down the flash somewhat using the proper powders for you caliber, length of barrel, and the size and weight of the cartridge you are using. In my experience, however, the majority of commercial grade ammunition is NOT specifically tuned for muzzle flash reduction, some military grade ammunition is designed to reduce muzzle signature but still requires a real good flash suppressor with NV gear. There are only a handful of real military grade flash suppressors on the market, most of them are junk.
The reason military grade flash suppressors are used by the military is to keep their NV gear from whiting out and to reduce their signature in the field for anyone else using NV.
You can manually reduce the gain to reduce the whiteout and have a much darker NV view, but if you are planning on shooting with NO flash suppressor or a crummy flash suppressor, as I said before, good luck. My handloads use a gunpowder that produces less flash than commercial rounds, but shooting it out of any of my rifles or SBRs with no flash suppressor or silencer produces a huge ten foot flash. This 10-foot flash is NOT good for night hunting with NV.
Also, all my GENIII NV gear works perfect with suppressors and zero flash from multiple shots.
Been loving the PVS-14/NV laser combo more and more lately with the silencer cans on and zero whiteout/blackout under any conditions, huge improvement!
Agree 100% here and basically what I've experienced per my postings above. We've been testing as mentioned and also shooting with NV and all sorts of gear for over 10 years. I mean take a AR out with no flash suppressors and see the FIREBALL out there! It shuts down MANY Gen 2 devices and some Gen 3's at that. ABC and Autogating can only do so much and huge fireballs of smoke and flash does not bode well for quick follow up shots.
SP also brings up a great point on powder used (if reloading) that will also show differences after shots with barrel length etc.
For others reading, think about day shooting as well. NV is well known not to see well in the fog, smoke etc., thus while thermal is used with fire depts. and others at night as well. Many shooters know at times the actual smoke in the air at the front of a muzzle. At night, this can be compounded even without a IR Illuminator being used.
Per my other posts, it's cheap insurance to get a flash hider at the very least, the best of course is a sound suppressor, it's the best of all worlds!
