Frenzy Plus 1x18x22 (SCRD-75) & Frenzy 1x26x32 (SCRD-79) Review

This is a review of Frenzy Plus 1x18x22 (SCRD-75) & Frenzy 1x26x32 (SCRD-79). from the-answer-is-42

Alright guys the long awaited micro red dot review is ready  I tried to be professional about this one as well like I did the 1-6 FFP review so be nice, this is my second long-format review for you guys.

The hot new trend in AR-15 optics is to use a red dot as a secondary aiming device along with your LPVO or MPVO scope so I want to do that too!

I have lots of LPVOs and have been looking for new red dots to pair with 1-6 and 3-15 scopes for close-range targets. I noticed that new for 2025, Vector has released options in their Frenzy red dot line to include a “mailbox” (ACRO) style model the SCRD-75, as well as a larger C-MORE STS/RTS style footprint called the SCRD-79.

Both models could be great potential options because I am looking for a large or unobstructed field of view. Traditional micro style red dot sights have smaller 20mm circular windows or less; and these have minimal frame obstruction with 18x22mm and 26x32mm windows respectively as per their website.

Both units weigh under 2.3oz and both use CR2032 coin batteries. The difference besides frame and form factor, is that the SCRD-79 is an open emitter (vs closed) and is a 6MOA dot (vs 3MOA) in the SCRD-75.

Frenzy SCRD-79

The SCRD-79 is the C-MORE style red dot with an open emitter design and a larger STS/RTS body. It has an extremely strong and robust frame surrounding the glass and houses a very

large 26x32mm viewing window. The 6MOA dot is large and bright - and the brightness settings are easily accessible on the left-side of the unit.

The battery is a side-load tray like the Holosun 407/507 models and other red dots which include this feature. All compartments are sealed and include o-rings – and even the emitter area has a bottom-drain to let water out if you use your optic in wet environments.

The downside of this Vector model in is that the elevation and windage adjustments do not have very tactile and positive clicks when adjusting. They are mushy but get the job done. I wont be adjusting the dot frequently, so this is not a huge issue.

I first tried this model mounted in the Vector SCFRM-29 45-degree offset mount also available on the website I got at the same time. This mount allows all of their red dots (besides micro footprint) to be mounted in the 45-degree position on a top rail and the field of view was fantastic. For my preference, though, the red dot was a little too large and stuck out too far for this purpose – but I had another job opening for the SCRD-79 as the primary optic for an AK-pattern rifle.

As a primary red dot, the SCRD-79 really stood out being such a lightweight, large, and robust open emitter optic.

There were plans to put either a Holosun 403B or Vortex Defender ST (from the pics) on this AK-style rifle but instead, the SCRD-79 took their place. The 6MOA dot was the same as the 6MOA Vortex Defender ST; and the field of view beat out the Holosun micro style optic by far.

Next, it was time to test the SCRD-75…

Frenzy SCRD-75

The Frenzy SCRD-75 is the ACRO aka “mailbox” style offering from Vector for 2025. Vector is doing an introductory sale on these plus website discount, so I had to try one as well.

This closed-emitter design houses everything inside the optic’s dual front-rear lenses and reduces the size of the frame and lowers the deck height by moving the red dot emitter to the top of the housing.

The windage and elevation clicks on this model are VERY positive and you can feel the ball bearing when adjusting – a huge plus over the SCRD-79 model. The overall window size is smaller – but is still a solid 18x22mm in size along with a very thin bezel and housing size which doesn’t obstruct the view much at all. I can imagine this would be great to co-witness on pistols.

Here’s some photos mounted in the 45-degree position:

Everyone has been using ACRO-style optics, and I guess I can see why after getting this one installed. The field of view and aesthetics are very nice with this style and model of optic.

The 3MOA dot is very crisp and the side-side (non-tray, micro style) battery access is easy to change.

The housing on this model is also very sturdy and instills lots of confidence in the optic’s construction. The anodizing and laser work on the optic has no issues at all and feels very good in-hand.

The glass on both models is very clear and I’m a fan of this enclosed model which is very compact and light vs a standard 20mm micro model.

For fun I mounted the SCRD-75 on a G19 slide and I really like it on there as well. Maybe an SCRD-75 as a pistol optic coming soon for me?

Overall, both optic options exceeded expectations and are most definitely not anything like the other options available all over the internet. Like all the other model’s I own these Vector products are all great quality and punch way above their weight-class in performance and quality like the 1-6 models and others I have posted previously.
