If your eye is close to the ocular side of the optic, everything is fine. This might be partially due to this effect I noticed with the SLx 1X. I rather have a straight riser, I do not see the need to have the cantilever at all other than the help bring the SLx 1X Cyclops Gen 2 closer to the shooter’s eye. While it clears the rear sight of my Daewoo DR200, this setup does looks a bit odd. Surprisingly, the objective lens is not as big as the housing.īelow is the SLx 1X MicroPrism in its tallest configuration. The tallest setup will clear most rear iron sights on an AR platform. I am not sure why but Primary Arms included cantilever risers that position the SLx 1X further back. The SLX 1X comes with a variety of spacers for any height you desire.

All SLx optics undergo rigorous field-testing during development to best serve you in any environment. SLx optics built our reputation for innovation, reliability, and value. The 1x MicroPrism is part of our SLx optics line. The SLx® 1x MicroPrism is an all-new advanced optical system designed from the ground up in an ultra-compact housing, allowing use of backup iron sights and magnifiers. In the past, prismatic optics did not allow the use of magnifiers or backup irons but the new Primary Arms SLX 1X MicroPrism can. Now granted the reticle will not do well at night and that is why there is illumination, or you throw enough light downrange to create contrast with your target and the etched reticle. The sight will continue to function even without a battery. While the SLx 1X does have reticle illumination, it does not need it.

Oh and let’s not forget the biggest advantage to an etched reticle – no need for power. This is due to the use of prisms and the short overall length of the optic. Some claim prismatic optics have a better light transmission than other optics. Especially if your reticle has fine detail. This is more difficult for an LED or laser-based red dot. The reticle is another boon to a prismatic optic.

The SLX 1X MicroPrism is an etched reticle so even when you turn on the red illumination, the reticle remains clean and crisp. Unfortunately, both varieties of red dots still result in a starburst-looking dot for those suffering from astigmatism. Red dots are traditionally laser-based or recently they are LED-based.

This new MicroPrism optic is a tiny package that works like a quality red dot. Well, now they have a new SLx 1X MicroPrism with the ACSS reticle. They have set themselves apart from the competition with their ACSS reticle. Primary Arms is known for making affordable yet durable optics that work.
