Most Helpful Positive Review Great quality
The pistol buffer and spring combo was just the thing my PCC needed to function correctly. With the previous buffer the bolt was traveling to fast and was causing the bolt catch to break. I was shooting 147 grn 9mm

Perfect for FRT

by Paul, from NH, United States Written on April 28, 2026
I dont have maxim defence brace but i bought this to work with similar one. It Works perfect on my SB tactical brace with my super saftey and with my Arcfire. Buffer is the exact same size so there's no problems so far after about 500+ rounds

Looks sweet, allows my bracelet to collapse farther in making my pistol shorter overall.

Fixed my Grendel

by Mark Amodio, Verified Owner from KY, United States Written on January 14, 2025
Was having issues getting my 6.5 Grendel to cycle properly and constantly. 20" barrel and rifle lenght gas system. Tied an adjustable gas block, but it wasn't a gas issue. Ended up being a spring/buffer issue. Tried a number of spring and buffer weight configurations and wouldn't run 100% of the time. Came across the Maxim products on Optics Planet, and I'm glad i did. I'm now running 100% with zero cycling or ejection issues. Quality is excellent on the Maxim products.
