The editor looks through something different from PAO
When I see special forces soldiers or police firearm units on the television these days I often look at the weapons they carry to see what’s new, and all too often they’re carrying Colt M4 variants. These tend to wear what appear to be ultra-compact prismatic scopes that deliver superior accuracy compared to open sights or red-dot units. The most well known of these is the Trijicon ACOG, a design that has been copied by many other manufacturers.
It’s a prismatic system which, as the name tells us, uses a prism to make a much shorter length than the traditional lens system. It does have its restrictions; making a variable magnification version is difficult, for example, so they tend to be like the one on test 4 x 32. Apart from being very compact, the benefits are that they offer a wide field of view and can be made very rugged – both features matter greatly in a combat situation. They also often come with a secondary aiming system, which in this case is a set of open sights on the top. The thinking behind this is that if your scope is damaged in a fight you’ll still be able to aim your shots, at short range at least.
The 4 x 32 Tri-Lume Prismatic on test is just 5.5” long, but weighs 456 grammes, so is far from light. It’s clearly intended for militarystyle rifles so uses the Weaver standard base that has thumb-wheel fittings, so no tools are needed for installation. To get the multi-aim-point reticle sharp in your vision, you use the one conventional feature, a rotating collar on the eyepiece. The reticle is etched onto the prism making it unbreakable and the scope is rated for all airguns and firearms, showing how confident the manufacturer is about its strength.
The reticle can be illuminated red, green or blue, each at three levels of intensity. The packaging reports that the scope is parallax-free at 100 yards, rather than the usual 35 yards for airgun use. This surprised me because I thought that prismatic scopes were parallax free at all distances, but perhaps I’m wrong. On the sides of the objective bell there are short sections of Weaver rail, presumably to allow lasers and torches to be added if they’re your thing.
The eye relief is much shorter than on a conventional scope and I couldn’t get this scope back far enough on my conventional sporting rifle, a Weihrauch HW110 to get the full sight picture. This tells me that it will be important to check its compatibility with your rifle before you buy. This is certainly a highly unusual scope and one that I’m sure will appeal to those with military interests.
The eye releif is very short so check compatability before you buy
