I just bought a 16" RRA entry upper with a KAC quad rail on it... i have the KAC foregrip on in, and when i was messing around with it i noticed the bottom section of rail is loose and works back and forth about 1/8th inch either way. There isnt any type of adjustment i can find and i was wondering if anyone else has this problem or if the is just normal?

| The KAC lower rail does not lock onto the barrel nut like the top rail does unless you buy the SAS rail separately (I did). Most two piece drop in rails will have some play on the lower side when you apply rearward or rotational force. It's normal even with a RAS. |
