Shane, without list a specific kit, we cannot give an accurate answer. The best thing to do would be to go to the manufacturers web site and find their contact info and ask them directly. Have a great day!

Shane, no ar pistol kit specified. If you post again with the model number or upc we can let you know if it'll fit your Remington ar or not. You can find the model number and upc under the products description. Thanks.

As James G. Said, it's best to contact the kit manufacturer to see what brands it will work with.
Good Luck!!

Hi Shane, it is always best to contact the Pistol Kit manufacturer to inquire about your specific model Remington AR for compatibility. Cheers and stay safe!
