well my primary arms 3x magnifer and flip mount arrived today. talk about fast service. i ordered in online on sunday and it arrived snail mail this afternoon.
my first impression is good. easy to mount and will sit over the magpul buis. when flipped to the side the buis can be activated for iron sight use. eye relief is short with a max eye relief being about 1.5-2". not a worry to me since the .22lr recoil is negligible. for larger calibers, the risk of a shiner exists. the magnifier lined up perfectly with my adco mirage tactical 2moa red dot optic on a cantilever mount. the magnifier optics are pretty decent for the price. i think it will work out well for up to 100 yards. the thing i notice is that my adco red dot is not perfectly round. when magnified 3x i can see how the "dot" isn't perfectly round. as the dot intensity is dialed up toward maximum, a starburst effect is noted. if the goal is to shoot quarter sized targets, the magnified dot will completely obliterate the target. for me, not a big deal as i won't be shooting at targets that small. i can however see why high quality optics cost so much. i can only assume an aimpoint dot at 3x magnification will retain more of a round dot appearance. with the magnifer rotated to the right, it is still well behind the ejection port and above it so i find it highly unlikely that it would cause any sort of malfunction with a spent casing being improperly ejected.
i had to move my red dot and my rear magpul buis so now i have to sight everything back in. oh well, i guess i'll have to send some rounds down range this weekend. i'm pretty excited to try it out.
i'll post a range report here on sunday afternoon or monday morning.
