A1 Steaksauce of a Buffer Beauty by jbuff, Verified Owner, August 24, 2025
Exactly what you would expect out of Geissele. Great fit and finish(except maybe the stamped plate) but that’s really a preference thing. Color looks great, really smooth.

Worth a shot for cheap build. by paul.0577, Verified Owner, December 2, 2025
It is good and reliable with good materials, only complaint i have is castle nut almost feels cheap and feels like about break any minute and endplate also doesn’t line up perfectly.
