Yes the feeding is improved, infact it is flawless.
Top rail is nice and low, perfect cheekweld with the KAC clone sights. The sights are functional but is for backup use only.
2 screws secure the top rail, be sure to degrease and locktite it secure after you settle on the side of the charging handle.
The rails are off spec and made 1mm wider than standard 1913 rail, will fit tight on certain optic mounts so be aware.
Side charging handle works well, but sits very close to the top rail, make sure you test clearance with optics/mounts or you will curse in blood.
Keymod side slots are cut proper, however forget attaching anything too close to the charging handle.
Magazine well is still too tight, back ridge needs fine sanding to feed Pmags.
Pmags are not the best choice as there is no over insertion stop. Make sure you insert and pull on an open bolt with Pmags.
Recommend STANAG mags as it is designed for, they are alot smoother in and out. Drops free after lots of insertions.
Rear cheek top cover fits a bit loose, DIY by adding material to fit tight if needed.
Ambi mag release, FINALLY.
