Great addition to any ar 15 lower. - Radical Firearms 16 in. 300 AAC Blackout Upper Assembly

FIT AND FINISH ARE EXCELLENT. INSTALLED WITHOUT ANY ISSUES. ADDED MY NEW FLIP UP SIGHTS AND A RED/GREEN DOT SIGHT. CAN SEE THRU THE BASE OF THE RED/GREEN DOT SIGHT SO I CAN STILL USE THE FLIP UP SIGHTS. ADDED EXTRA RAIL MOUNTS TO THE SIDES AND BOTTOM OF THE FREE FLOAT HAND GUARD. ADDED 2 ADJUSTABLE BIPOD LEGS THAT ATTACH TO THE SIDES OF THE FREE FLOAT HAND GUARD RATHER THAN ON THE BOTTOM OF THE HAND GUARD WHEN USING A SINGLE BIPOD. SINCE THE LEGS ARE ON THE SIDES, THE RIFLE IS A LOT MORE STABLE. EQUALS BETTER SHOT PLACEMENT. THEN I ADDED A LIGHT/LASER UNIT TO THE FRONT BOTTOM RAIL. THE LAST THING I INSTALLED WAS A 30 CAL TANKER STYLE MUZZLE BRAKE. IT LOOKS A LITTLE BIG ON THE END OF THE BARREL, BUT IT WORKS LIKE A DREAM. FOLLOW UP SHOTS ARE SO MUCH EASIER, ITS SCARY. COULD NOT BE HAPPIER WITH THE RESULTS.
