5 of 5 450 Bushmaster upper assembly December 16, 2020
Reviewer: Guy from El Dorado, CA United States  
Very satisfied with this upper. The slim hand guard is  desirable to grab and grip, also to have the option to mount fold down sights. I wanted the option to add my own bolt assembly and this purchase had just that. If you're shopping for 450 BM upper, you won't be sorry with this one. It's worth every penny.

Reviewer: Rhett Lee  
Love the upper, functions perfectly, no problems (I’ve only had it for a few weeks and haven’t even put 100 rounds through mine yet but it’s exactly what you’re looking for if you want a 16 inch bushmaster
