The ERC comes standard with both the Battle Tested Electronic Grip Frame and Rip-Clip™, allowing you to experience the fastest possible rate-of-fire. The Rip-Clip force-feed loader system utilizes HALO™ technology, including the built-in Rip Drive™, to throw a wall of paint towards the enemy.

I own this gun and it does really well on a wooded field, but i play with it on an airball field and with it’s speed it does just fine, and it’s a very strong gun…It is a little heavy but it’s worth it
I have just googled military standard 1913, and I have found that it specifies the dimensions for a picatinny rail. Any paintball or airsoft marker/gun that has a functioning picatinny will conform to standard 1913. It sounds very good, however, to someone who does not want to do research or who is not very bright and easily swayed by advertisement. It looks great in there, making the marker seem almost like a true weapon, which makes a fantastic advertisement point as long as your target, of course, does not know what standard 1913 is. But anyways, amazing marker, will be purchasing one myself within the next month.
Thanks for producing such an amazing product,
Max
