I am sorry to necro but I have an important question. Hello, I am new to this forum as well as a new owner of a GSG 522 SD. I am thinking about modding it with the ICS lower but need to know if it is durable and can take the small kick from the .22. Has anyone had any issues AFTER the mod? I have played airsoft for about 6 years now and know the rifles well but there is no kick in an AEG so I need to be sure. Thanks for any help that can be given and again, I'm sorry about the necro but I need to know it this thing is going to explode in my face :-)
