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.

Great large frame AR option

Review by Casey on 24 Jun 2025 review stating Great large frame AR option
The fit and finish on the receiver set is great. I’ve built on seekins, Geissele, and SiCo AR15 receiver sets, but this set is the best fitting. I would’ve given it 5 outta 5 stars, but when I built up the gun I’ve had some annoying issues with Centurion’s hand guard and their Customer Service. They are working to get issues resolved, but there has been multiple issues in a month long resolution. Not a dig on the receiver’s quality or Rainier in getting it shipped to my ffl in a timely fashion because both were solid.

Staccato CS W/PMM Comp

Review by RG2 on 21 Jun 2025 review stating Staccato CS W/PMM Comp
Sent my CS to Staccato to add a threaded barrel with the intent of adding a comp. Decided on a PMM comp as they had one specifically for the C model. Both the the C and CS are the same at the muzzle but this was listed as not working on a CS due to the shape of the guide rod end as mentioned on another review. As the slide racks the corners of the stock guide rod would make contact with the comp hence not compatible. The DPM System not only fixed this but gave me the opportunity to dial it in. I am very pleased with this set up. It has been great with no issues and is an improvement over stock. The fit and finish are top notch!
