"ive had this fore grip for a few days. hours after i got it and was mounting it, the screw holding one of the legs in place broke off. it was easily fixed by sawing a slice into the metal leg and using a zip tie. i use this on my DMR M14, and it works very effectively, and works best when transitioning from crouched to prone, and when leaving your rifle on a table. i recommend buying this, regardless of it breaking, because mine was just low quality."
