No you should be all right. Nothing their is spring compressed. Watch out though for some screws.
YouTube - Airsoft GI 101 - How to Tighten the Buffer Tube on the M4A1
This video should more helpfully showcase what i mean. All you would do is instead of tightening it, you will loosen the screw and slide off the buffer tube and leaving you with the end plate, where you can replace the stock one with the Magpul ASAP.
Hope i helped.
