Maybe they are willing to trade pain for accuracy and a gun shouldn't be built like that for a person to resort to such stupid gimmick.
Flawed ergonomics, The Buttstock is still horrible and beyond unusable it needs a cheek wielder, handguard is outdated at its best which should be replaced with a MLOK.
While the solution is bad, You can't do much when PLA has never addressed the outdated ergonomics.
Thankfully it isn't as flawed as the MCX Spear such as Poor Quality, Mag Feeding Issues, Overweight with Ammunition weighting too much, Charging handle accidentally being pulled off, Scratches and dents inside the gun after a few rounds.
No gun is perfect but Heckler Koch is the best company, SIG is overrated lots of quality issues.
