BSA is an optics leader and they’ve been making dot sights for years. The BSA 30mm Red Dot (or RD30) is one of the older red dot sights in BSA‘s optics arsenal.

It’s been around for about six years and since then the competition has outclassed it in some key respects, especially in the areas of concern for AR-style weapon users.

BSA-made optics enjoy a good reputation for reliability, but not always durability. The BSA 30mm Red Dot doesn’t come equipped with any special weather-coating or ruggedness features.

It isn’t advertised as “shockproof” or anything like that. The assembly is protected by a polymer sheath and the whole thing weighs just under a third of a pound.

For most shooters the more important thing to note is that the lenses aren’t coated with any light-filtering materials. As a result, “transmission,” or the amount of light the objective lens lets into the tube, is almost 100%.

The BSA 30mm Red Dot does have a sunshade that projects over the front a bit, but that’s all this sight offers as far as light reduction goes. The lack of any light-filtering coating on the lenses can make the reticle a lot harder to see under bright conditions or glare.

Some users report needing to set the dot to full brightness just to make it out on a sunny day, and consequently draining the battery more quickly.

bsa red dotThe specific complaint from AR-type weapon users is that the mounts on the BSA 30mm Red Dot can’t handle the heavy recoil, at least not consistently.

The mounts are very adjustable, and the BSA 30mm Red Dot installs easily on most rails making it great as an AR 15 optic.

The mounting screws have received a lot of complaints for loosening up under recoil. Some users report having to tighten them repeatedly during long target practice sessions.

Others report they strip easily. The mounting system itself also rides pretty low on the rail, so you might to get a riser or make other adjustments depending on the weapon.

The BSA 30mm Red Dot is sighted for 50 yards out of the box. The field of view at 100 yards is 68 feet, and the accuracy is 5 MOA.

The elevation and windage knobs are located on the top and side, and the brightness knob is forward up top. MOA adjusts in 1/2 clicks. The brightness of the dot reticle adjusts to the semi-standard 11 settings.

In sum, the BSA 30mm Red Dot is a reliable red dot sight which has been around for a while, and, while its price may have come down over the years, the quality of the competition has gone up.

There are some doubts about its suitability for high-recoil, AR-style weapons. Still, there are no questions about the long-term reliability of BSA’s optics. Some owners of the BSA 30mm Red Dot have had theirs for years now, and they are remain satisfied.

The fact is there are better and newer dot sights than this one on the market today, and unless you can pick a BSA 30mm Red Dot for less than $30 dollars, you might want to look elsewhere.  For that price you’ll find other options in our cheap red dot buying guide.
