Product is fine but shipping took 6 days instead of the 3 they estimated. Not a huge deal but worth mentioning.
Justin C. (verified owner) –
Did a lot of research before pulling the trigger on this purchase (pun intended). Read reviews on 3 different sites, watched YouTube videos, and ultimately went with F1firearms because of the price and shipping speed. Not disappointed. Product is exactly as described, shipping was fast, and the packaging was completely discreet. Already eyeing a few more items in their p80 kit section.

I don’t write reviews often but F1firearms deserves one. The Aero Precision RL556v3 80% AR15 Lower – OD Green is exactly what I was looking for. Good build quality, snug fit on my G17 Gen4, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.
