For sale is a NIB BCM 10 inch free float quad rail. I opened the package and noticed it was too long for a build I am completing. The small baggie containing the factory supplied blue Loctite and allen wrench was opened but is still included, along with all factory hardware for installation. Purchased from Optics Planet as a final sale item so they will not accept returns/exchanges (Don't know why I still give them money). I can ship to lower 48 on your dime or meet FTF for $125. My failure to measure twice and order once is your gain. Thanks.
