Aimwin PE330

Review

Enclosed micro red dots are not a new thing. However, Aimwin is a fairly new company in the optics market. One of their newest editions is the PE330 enclosed red dot. The PE330 red dot comes with an enhanced feature set and mounts directly to RMSc style footprints.

As mentioned, the Aimwin PE330 is an enclosed emitter style red dot optic. This gives the PE330 some advantages over open emitter style red dots. It protects the internals from dust, water, and any other debris. It also makes the lenses easier to clean. Living where I live, having an enclosed red dot is a big advantage because of the rain we get in Oregon. The water doesn’t get trapped inside the lens like on an open emitter style. So if you need to wipe the water off, it is just a simple wipe, not a scrub and soak.

The exterior of the Aimwin PE330 is 6061 aluminum. 6061 style aluminum seems fine for this type of optic. The hard anodized aluminum exterior helps to make the PE330 pretty durable. The PE330 also is water resistant, nothing is water proof. Aimwin specs it out as IPX7, which is submerged at 1 meter for a 30 minute time frame. This is pretty standard on these styles of red dots. It didn’t leak on me, but I also didn’t swim with it on.

When dealing with micro red dots, the mounting footprint is super important. The Aimwin PE330 uses an industry standard RMSc footprint. This footprint is what a lot of micro compact pistols use for direct mounting to the slide. Oddly enough, the RMSc footprint is also used on some 1911 and 2011 full size pistols. Having that industry standard footprint really makes the PE330 standout for mounting on various styles of pistols. Included with the optic is a bunch of various size mounting screws. So finding the correct screw for your mounting surface is super easy. I always like it when companies put in those extra mounting screws, that way I don’t have to hunt some down in my screw bin.

When it comes to powering the PE330, Aimwin uses a CR1620 battery. This is a slightly thinner battery than the CR1632, which is used in a lot of RMSc footprint red dots. Aimwin states a 20,000 hour battery life. So even though it isn’t as long as others, it is still plenty. Aimwin also designed the PE330 with a side load battery. So when you do change that battery, it is super easy to do and will not affect your zero. Something I haven’t seen with other red dots is that Aimwin includes extra battery tray screws. I will probably lose the extra screws before I actually need to replace one, but they are there just in case.

The PE330 isn’t just a red dot, it is a multi-reticle system. It includes a 3 MOA dot and a 40 MOA circle. You can combine these into a dot only, circle dot, or just a circle. To do this all you have to do is hold down the brightness up button for a few seconds. For brightness adjustment, there is a soft touch pad on the left side of the optic with + and - labels. The PE330 has 11 brightness levels. The lowest 2 are night vision compatible, while the other 9 are daylight bright. To adjust the position of the reticle, the PE330 uses a small standard screwdriver. It also has actual clicks for adjustment, not just the turn and guess style. Each click is 1.5 MOA.

Aimwin has their auto on feature called “AIM Awake”. As one can guess, this is Aimwin’s shake awake feature. After a few minutes of not being moved, the PE330 will go into a standby mode. When movement is detected, the dot automatically turns back on at the same brightness level it was adjusted to. This feature gives more battery life to the optic. In today's red dot market, every optic should have this if it uses a battery. I am glad Aimwin includes the Aim Awake feature.

For the review, I mounted the Aimwin PE330 on a Tisas 1911 Double Stack. The window size of 23 x 16 mm worked well on this pistol. It is not the largest window, but it was very useful. I also noticed that the dot is very clear. Some of that is probably due to the glass used on the optic. I was pleasantly surprised at how clear the glass was. I couldn’t notice any color change or tint to it. Because the PE330 is a little wider than smaller RMSc red dots, it does hang over the sides of the slide. It is definitely noticeable, but does not hurt anything at all. That is a price you have to pay for a larger’ish size micro red dot on a thin 1911 slide. I don’t really care for the 1.5 MOA adjustment range. Yes it works, but I would like a finer adjustment, maybe something like a 1 MOA adjustment. With that said, I didn’t have any problems sighting in the pistol. I also haven’t had any problems with the sight itself, even with a ton of rounds being shot for the Tisas review itself.

Anyone looking for a reasonably priced, enclosed, micro red dot should go take a look at the Aimwin PE330. It uses that industry standard RMSc footprint for mounting and has a side load battery. The red dot is very clear on whatever reticle option you choose, may it be a dot or a circle. Plus it is priced right for anyone. From beginners just getting into the red dot market, or experts just needing another dot, the Aimwin PE330 might be the one you're looking for.

Great deal

I’ve tried a fair number of pistol red dots over the years, and I picked up the PE330 mainly to see how it would hold up as an enclosed optic. After putting some rounds through it, it’s been solid and predictable, which is really what I want from a handgun optic.

The enclosed emitter definitely helps when conditions aren’t perfect. Dust and debris haven’t been an issue, and the sight picture stays usable without needing constant attention. The glass looks good overall, with no distracting distortion, and once it’s zeroed, parallax hasn’t been noticeable in real shooting.

The reticle setup makes sense. The larger circle helps you find the dot faster, especially when drawing or moving between targets, while the center dot still gives you enough precision for slower, more deliberate shots. Under recoil, the dot is easy to track and comes back into view naturally, which makes follow-up shots smoother.

Battery life hasn’t been a concern thanks to the motion-activated wake feature, and I haven’t run into any random shutoffs. Mounting it on an RMSc-cut slide was quick and straightforward, and it stayed tight and held zero through multiple range sessions.

All things considered, the PE330 is an easy optic to live with. It does what it’s supposed to do, feels intuitive behind the gun, and works well for regular range use or for shooters getting comfortable with enclosed pistol optics.

Enclosed Emitter

Red dot Review

In today's market, there are a bunch of good pistol style red dots. They basically come in two categories: open emitter and closed emitter. Aimwin recently released their PE320. The PE320 is an enclosed emitter red dot with a multi-reticle system and a solar fail safe.

As with any quality red dot, the Aimwin PE320 comes with everything needed. In the box you get the optic, a battery, extra screws (including one for the battery tray), wrenches, cleaning cloth, etc. Probably the most important included item is the Acro to RMR adapter. This gives you the ability to mount it on anything that uses the RMR mounting footprint. There are lots of pistol options using a direct RMR footprint.

Mounting the PE320 is pretty straightforward. However, it does come with two options. If you happen to have something with an ACRO mounting footprint, like a riser or a plate adapter, you can mount the PE320 directly to that. If you have a direct mount RMR cut/footprint, you can use the supplied ACRO to RMR adapter. This is what I did. Just screw down the RMR plate onto your slide and then clamp on the PE320. It's really that easy.

Now that the Aimwin PE320 is mounted, you can take it to the range. To initially turn on the PE320, just click the “+” button. The buttons to control the PE320 are located on the left side of the optic. These are rubberized raised buttons labeled “+” and “-”. They are pretty large and easy to use, even if you are wearing gloves. Of course, tapping on a “+” or “-” button will increase or decrease the brightness of the red dot. There are 11 total brightness settings, the 2 lowest are night vision compatible. Now that the PE320 is on, you can sight it in. A nice feature on the Aimwin is its click adjustable windage and elevation screws. Each click adjusts the point of impact 1 MOA, which is fine for these types of red dots. Now that it is sighted in, and you want to completely turn it off, just hold down the “-” button until the dot disappears.

The PE320 uses Aimwin's “aim awake” feature. The “aim awake” is their auto on/off feature. Once you turn on the PE320 this feature is enabled. Aim Awake works like any of the other auto on/off systems. After the optic sits idle for a short time, the dot will turn off. Once you barely move the optic, the dot will turn back on. The aim awake feature helps with battery life, giving the PE320 around 50,000 hours of run time. I am a huge fan of these auto on/off features.

Aimwin's PE320 is not just a red dot. It features a multi-reticle system. So you get the option of either a circle dot, just a circle, or just a red dot. If using one of the options with the circle, the circle also has little hash marks in it that are located every 90 degrees (similar to an Eotech). To cycle through these 3 reticle options, just hold down the “+” button until it changes. The PE320 uses a 36 MOA circle with a 3 MOA dot, or any combination of the three. I like having reticle options and the PE320's are useful for whatever you need or want.

The multi-reticle system of the PE320 is housed inside a large window. How large is the window? 0.94 inches wide by 0.79 inches high. It's a big window, which is really nice for finding the reticle. However, because of its large window, the PE320 is a little wider than a lot of the enclosed ACRO footprint optics. This isn't bad or good, it really just depends on what trade offs you want.

The last notable feature of the PE320 is the solar panel on top of the optics housing. This solar panel adds a “solar failsafe” to the optic. So if your battery is low, and there is enough light, you will still see the reticle. The Solar Failsafe also works when the battery is completely dead, as long as there is enough light. I tried it with the battery out, and the reticle still comes on under normal room lighting. Don't expect it to work in a dark room without a battery. The Solar Failsafe is a nice option to have, especially if you forget to change the battery out once a year. When you do need to change that battery, the PE320 uses a side mount battery tray for easy use.

I mounted the Aimwin PE320 to a Polymer 80 with a Grey Ghost slide. This particular slide is cut to direct mount an RMR footprint. So I ended up using the PE320’s ACRO to RMR plate. I chose this pistol because I use it in various different forms, one of those is using a Recover Tactical 20/80 brace system. This let me try out the PE320 in a chassis style system and as a standard pistol. I put a ton of rounds through it and even beat the crap out of the PE320. No loss of zero and no other problems, even when using the optic as a slide racker off the benches at the range. With the PE320’s adapter plate, the red dot does sit a little higher up on the pistol, but still below the top of the slide. If you want the PE320 to co-witness with iron sights, you will probably have to get some suppressor height ones. Those still might not be tall enough to clear the PE320’s deck height. Speaking of size, the PE320 is large for a pistol style red dot. Not so much height wise, but more width wise. It definitely is wider than a standard Glock slide. I only see this as a problem if you are carrying it inside the waistband. On a rifle, this could be a bonus. Especially since the window size on the PE320 is fantastic. It made finding the dot real easy. I like the 3 MOA dot size, it is a good compromise between speed and accuracy. Since I live in Oregon, it also rains a lot here. Having an enclosed system also makes it way easier to wipe the rain off of the lenses.

If you are in the market for an enclosed style pistol red dot, the Aimwin PE320 might be worth looking at. It has a decently large window and different reticle options. Being larger in size, it would also make a good rifle dot. If you forget to change your battery, it might still work for you thanks to that solar failsafe. It is also durable and held up to my abuse. So go check it out over at Aimwin.com.

Very Nice Enclosed Optic

Just picked this up for my H&K P30L. Had to change the optics plate (Langdon Tactical cut) to an ACRO mount, but it fits perfectly on it and locks down solid. The body appears to be pretty durable and stout without being overly heavy. Controls are nice and large so adjusting brightness and/or choosing dot style is pretty easy. ACRO mounts are probably the easiest installation of any of the footprints since it works like a pic rail. No screws into the plate to worry about getting torqued just right. It does really need a torque spec listed for the clamp screw, though. Never really liked "make it tight, but be careful not to over tighten it" with no spec for what "tight" is. Dots are extremely bright on the max setting and much calmer on the lower settings. Again, it is nice to be able to choose different reticles for different situations. Battery is side loading, which is nice as you don't have to remove the optic for swaps. Only issue I have with the battery compartment is that the tiny screw that holds it in place seems easy to lose as it is not captured. So be careful swapping batteries. We'll see how it does at the range this weekend at holding zero. Adjustments are nice and tactile with just enough resistance to turning to make me think they will stay put pretty good. May wind up being awfully high if you were to use the RMR to ACRO adapter that comes with it on most RMR cut applications. But sits at a nice height on the ACRO specific plate I have installed.
