Utg deluxe ergonomic foregrip - UTG Pro Ergonomic Ambidextrous Vertical Foregrip

I like this item, as to how it mounts to the rail. The problem I had it I had this foregrip matched with another UTG product and it did not fit. It appears the lower rail set included in the Leapers UTG PRO AR15 SuperSlim Free Float Handguard does not fit this slot. I had to use a different rail section to attach to the guard so this would work. After much research, I appears as if UTG does sell the rail section in the correct spacing. I like the product, just wish I would have known to get the different sized rail section when I ordered the two products.
