The Gapper fills the void between the trigger guard and the top of the pistol grip on your AR-15. Not only does it cover the sharp edges that are an irritation to many shooters, but it also gives the bottom of the trigger guard a more complete and finished look. This solvent resistant rubber "Gapper" easily installs and is held securely by friction.

Finishes everything off perfectly. And your finger still feels good after 2or 300 rounds. Simple, yet very effective and you can bin the foam ear plug that you stuffed in the gap.
I attended a tactical rifle class without the Gapper. My middle finger was a bloody mess. I used bought the gapper and the went through another class. What a difference. My finger wasn't torn up. Great product. I would recommend it to anyone.
