I heard their were different flash hiders used on the P90 (earlier vs newer).
Which hider is newer and which is older?
The Stryker one: http://store-strykerenterprises-com....ider_p_13.html
The CMMG one: https://www.cmmginc.com/shop/flash-h...le-m12-x-1-lh/
Looking on FNH's site, I see they use both, randomly.
Which is correct for a Gen2 USG?
