I have a G3 and I want to just attach an angled foregrip on it. Any recommendations. Could I just drill one rail to the bottom? Or would that mess up the gun?
Look at the under side of the front end of the G3, there should be two small holes in it... measure the length between the holes.... Find a singular rail to run between them. mount the rail.... mount the AFG.
Get a cheap springer and farm the rails off of it. Then drill through the handguard (discreetly) and affix with bolts/nuts. I did this for my OLD G3 SAS and it held a PEQ box quite well. PEQ looked gay, but the rail held up (and it was plastic!)
