For compact not full size

Review by Noel G. on 26 Jun 2025 review stating For compact not full size
Says it's for made for the full size in the description, IT IS NOT, it is for the compact. It will still fit the full size, but it will look funny with the slide sticking out about half an inch.

No weight savings

Review by Christopher G. on 26 Jun 2025 review stating No weight savings
I got this as an alternative to a traditional upper with ejection port cover, forward assist, ramp with the hopes that it would be lighter. But putting this on the scale next to an Aero Precision with all the accoutrements attached, this came in at the same weight. So it's great if you're looking for a no-nonsense upper that is sleek and won't get snagged, but less good it you're goal is to shave off an ounce.
