Which Holosun reticle should I go with?

	2 MOA dot (407C, EPS 2 MOA, EPS Carry 2 MOA) - The 2 MOA dot is the smallest dot Holosun offers. It is best for precision shooting, but may be hard to aquire quickly for shooters that are new to red dots. Regularly practice drawing your weapon and aquiring the dot and you'll be comfortable in no time.
	6 MOA dot (407K, EPS 6 MOA, EPS Carry 6 MOA) - The 6 MOA dot is the larger dot Holosun offers. The 6 MOA dot is said to be slightly easier to aquire since the dot is larger, but won't be as precise at longer distances over 50 yards. At a standard close range distance (3-7 yards) there is not a noticeable difference in precision and a 6 MOA may actually be preferred for faster target acquisition and easier tracking of the dot.
	MRS - 2 MOA Dot & 32 MOA Circle (507C, 507K, 508T, 509T, EPS MRS, EPS Carry MRS) - MRS stands for Multi-Reticle System. The reticle features the 2 MOA dot for precision and the 32 MOA circle which can be helpful for acquiring the dot and larger targets. Holosun optics with MRS can toggle between dot only, circle only, and circle dot.
	CRS (507Comp) - CRS stands for Competition Reticle System. CRS is an enhanced multi-reticle system with four components including a precision 2MOA dot, an 8MOA circle, 20MOA circle, and 32MOA circle with multiple combination settings to suit individual shooter preference.
	ACSS Vulcan - Chevron (507C ACSS, 509T ACSS) - The ACSS Vulcan Chevron reticle features a 10 MOA aiming point surrounded by a 250 MOA outer circle. This circle indicates the relative position of the chevron when the sight is off-center. At an average arm’s length (27”), the ACSS Vulcan will only show its chevron when properly aligned. If the sight is canted, the outer ring comes into view, guiding the user back to center. This eliminates the ‘searching’ problem on traditional dot reticles. The chevron has the added benefit of allowing the user to better target at range. For example, with 9mm, when the tip of the chevron is zeroed at 25 yards, the bottom of the chevron can be used to aim at 100 yards.
	ACSS Vulcan - Dot (507K ACSS) - The ACSS Vulcan Dot reticle features a 3 MOA dot surrounded by a 230 MOA dotted outer circle. The outer circle is not visible when the dot is centered. When your aim is off-target, the edge of the 230 MOA outer circle guides you back to center. This eliminates the ‘searching’ problem on traditional dot reticles.
