First a link to the gun, http://www.airsoftgi.com/product_info.php?products_id=9608 Second a link to the upgrade, http://www.airsoftatlanta.com/ICS_MP5_A4_A..._shopping_feeds Can I take the forward grip off of the MP5A4 and replace it with the RIS rail? Also, are there any problems with this gun? As in durability or the blowback? Are there any problems with the blowback breaking? Also, please tell me of any problems with the gun. I want to know if anyone has had any problems the gun ceasing to fire or breakage or anything of the sort. Please respond, I am hoping ot get this gun and the rail system.

You might find faster and better answers in the AEG section of the forums.

G&G makes awesome quality products so you should not have a problem with the durability of the MP5. Pneumatic blowback isn't as great as GBB but it is still a nice feel. As for the grip, it might be compatible, your best bet would be to contact AA or ASGI and ask.

Thanks for the input!
