I see there hasn't been much activity on this thread in last few years! Posting a LM6 which I have had for around 20 years. Hated the foregrip as it was a bit loose - most of them are if I remember from the army. Also felt uncomfortable as a foregrip - I have small hands. We trained on the R1 (FN) initially and then on the R4. Much preferred the R1. Put a rail system foregrip on the R6 and red dot. Also posted the Galil grandfather - my Russian made AKS (Type 3) dated from 1957. This I have kept original!
