Will this work on 300 blackout and 308? Expert Answer

The Manticore Arms Eclipse 5/8x24 Flash Hider For AR-10/SR-25 could be used for a 300 Blackout rifle as long as the barrel is threaded for 5/8x24.

very high quality flash hider by dan, Verified Owner, April 9, 2025
Built a 16” lr308 and had some flash visible through my scope. Bought for the price and it’s construction. Pretty much eliminated any flash and I don’t get the boom associated with a compensator. Recommend!
