BudsGunShop.com - 50 ae desert eagle

Hi Michael and welcome. It will fit an accessory railed 50 AE Desert Eagle. The designation would change from a Handgun/Pistol to Any Other Weapon (AOW) and you would need to register it with the NFA and pay the $200 Tax Stamp. The process can take up to 6 months to complete. Cheers and stay safe! budsgunshop.com/nfaguidelines.pdf

Michael, yes, as long as you have a picatinny rail version desert eagle this will fit no problem. Not sure if you're aware but adding a vertical foregrip to a pistol would reclassify it from a pistol to a AOW/any other weapon and would require you to register it with the ATF and pay a $200 tax stamp fee like you would for suppressors. Hope this helps.

Michael, yes sir, this will fit as long as you have the model with the accessory rail.
Stay safe & have a great day!
