If you are going to get an EGW mount make sure you buy better quality screws and throw the ones that come with the base away. I stripped out the heads on 3 of 8 trying to take my 20 MOA bases off my SA and LA trying to swap barrels. Now I have to try to get the screws out and that is going to cost me$$$! The bases themselves are great, but the screws will put the screws to you!
