Cobra RD3-006X-1 Green Dot Sight - Compatible with Doctor/Venom/Fastfire Red Dot Footprint

I purchased both the Rd3 -012g &RD3-006A.both are very nice well made and mounted securely on weaver style rails..you can’t beat the price/quality. These are both mounted on S&W 22A’s.. sight in was quick ,and both are holding there zero no problems. I did have problems with packaging on the oo6a whereas it was previously purchased and didn’t have any thing but the sight with a dead battery in it .Amazon helped out with this .I’m gonna contact seller and see if I can get the rest of the contents. Screw driver ,instructions etc.. over all I see no reason to spend mega bucks on other sights when the quality of these match or exceed them ..I spent $350 on a so-called top of the line brand and managed 3 yrs of usage before it quit. Co wanted $120 to repair..got the o12g for that price

It’s pretty nice, easy to install and fit perfectly. Will update on performance and durability once I try it out.

I originally wrote : "ok price and ok delivery time. It works as advertised. Works as advertised". This AI rejected it. I have wrote the same thing in the past on other products. What is the problem now with this review?

Currently using this on a S&W M&P 40. Have fired about 500 rounds through it in the past month and it hasn’t skipped a beat! Holds zero perfectly. Group size was cut in half. If you hesitating do yourself a favor and buy it. You will not regret it Update: I sent in for the “free magnifier” they sent me a garbage magnifying glass.... don’t bother

This sight indicated on the box it was the A model. After trying this sight for a few days I decided to return it. Pros: Nice build, Nice Green Dot. Cons: On-Off Button is a pain. For some reason it is hard to find with my finger - I need to look at it to find it. The adjustment direction marks seem backward to me but I guess they are correct if you think about the direction the bullet needs to move and not the direction the DOT needs to move. Using a screwdriver head instead of an Allen Wrench is also inconvenient and awkward. Also having to LOCK the final setting is an extra thing to do. The battery is below the sight and will require sight removal to change. I never got to the point of taking it to the range. I just returned it. I tried both the A and B Models of this sight which seem identical even though the B Model was suppose to have an improved Front power/brightness switch???

I have a full-size red dot scope on a Ruger mark IV, and love it. This was for Berretta 92FS. It's harder to acquire than my full size red dot, which I probably should have anticipated. It has a little bit of a double dot, which I'm not sure how/if it can corrected. I had some trouble with the base loosening at first. Use thread lock on the base screws. I also had to take a little off the top of the hammer release which protrudes from the top of the slide on the 92FS when fired. The base has a small relief for this, but it wasn't quite deep enough, and it made more sense to take a little off the top of the hammer release. Updated after 3 years. Have to say you get what you pay for. There are two wires from the battery/switch to the laser, which are soldered to board the laser is mounted to. These wires have come off twice now, requiring some very delicate re-soldering to reattach. If I fix this thing again, I will probably pour epoxy on the wires so the recoil doesn't pull on them and detach them again (hopefully). Should have been that way from the factory. Probably should have used something lighter for the wires so they didn't keep coming off. But I guess thats why it's only $70. Would probably work fine for an air pistol, but definitely not able to handle the G-loads of a semi-auto pistol. Bought a Vector instead, we'll see how that holds up.

This is a fine red dot optic, small, rugged appearing, easy to install. It was delivered on time and in good shape. I give it a conditional thumbs. (just because I have no idea as to its long term durability one week out)

For the money these are great sights. There are a number of different versions of them here and on the bay, and I've tried a few of them with mixed results. In comparison to far more expensive sights I haven't observed any functional difference. Construction is very good, and the adjustments have arrows/marks to aid getting them sighted in along with the flat head screws (and screwdriver). So far no issues, but i have them only on a 22LR and an air pistol, so I can't say anything about durability under recoil.
