If these were built like other forearms Ive seen, that might be ok and you could definitely glue toward the back instead of Velcro however, when test fitting these, I quickly realized I cannot fasten them at the front near the wrist with anything other than Velcro, snap, magnet, etc. or else my hand will not go through. So I decided to leave them loose at the front much like other forearms are left unglued just enough to be able to get your hand in. The gap really isnt that bad at all. Anyone can do as they please for sure but, I'm just saying, unless you have really small hands and are a very thin build, be carefull how you fasten these forearms.
