Without the magwell and using the the Springer basepads, it fits the box easily, no need to compress the sight. Legal for SSP as well, it's the gun I made SSP Master with in 2018. After a year of farting around with CO I'm back shooting SSP. Like the new 15 rd mag capacity. BTW this is not an Elite but I have 2 and they fit the same way, just like Old Faithful better.
