Nice but!

Nice machine work but colors of hand guard and upper are different. Don’t waste your time trying to match, they’re painted at 2 different places. Kinda dumb how they are not close at all!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Great finish and quality workmanship

I always buy Aero Precision uppers and lowers. Never had a problem with fit or finish of any of them purchased, all top quality. Parts kit always fits good with no problems. FDE Cerecote matches closely with buttstocks and grips in FDE by other manufacturers. Aero's customer service or technical support is OK, but not perfect.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
