WPZ LCR Base Plate for Lancer Systems AR-15 Magazines is a complete magazine base plate and floor plate replacement with a little extra flair. This is a new design to bring you a more secure fit to your base plate. What's in the box (multiple of packs purchased): LCR Base Plates Floor Plates Instructions: Empty magazine of all rounds Flip the magazine upside down Press down on the base plate (oblong grey part in center) in the magazine. While holding the base plate depressed, slide the OEM base plate off SLOWLY while keeping your thumb over the opening. Not doing this slowly while keeping your thumb over the opening may result in the spring and floor plate in the magazine launching at your face. Not our idea of a good time or experience. After you've slid the OEM base plate off and avoided the spring launching at you. Remove the OEM Floor Plate attached to the spring. Pay attention to the orientation as you'll have to do this in reverse order in the next step. Take the LCR1 Floor plate and attach it to the spring so that the oval ring shape is facing into the mag and the rectangular piece at the end is at the spine of the mag. Once that is complete proceed to the next step. Give it a little tug to make sure it's on all the way. Push the OEM spring and floor plate back into the magazine and keep it depressed below the opening. Keep your thumb on it and hold it down. Take your LCR1 plate, properly orient it to the slots and slide it on until you hear it snap in. Check for secure fit by trying to move the plate by pushing it back off the magazine slot with some force. You may hear it and see it move back about 1mm, this is normal.
