Beware of thread locker - great experience

Installed this on my 92xi. Great product, however there is far too much solid thread locker on the bolts from the factory. So much so that both bolt heads snapped off during assembly. The only reason I am rating five stars is because Optics Spot support was incredibly helpful and prompt in resolving the issue on Beretta's behalf. Thank you Optics Spot. If not for the support staff I would be very unhappy, such an oversight is unacceptable from a premium brand.

Much better plate and screws then Beretta's offering.

The customer service was exceptional in helping me decide which company to order this plate from. Beretta answered my call, but had no solution for their inferior, soft screws. After 500 years I would think they could have solved such an easy problem, The plate arrived a few days earlier then originally scheduled. The plate fit the Beretta APX A1 RDO perfectly. The plate was rugged and the screws supplied were much better then the soft junk screws that Beretta supplies with their plate.

Super Sights

Hat bei mir die werkseitigen Suppressor-Height-Sights ersetzt, die waren mir zu hoch. Jetzt zusammen mit dem Frenzy SRCD-82 für mich perfektes Zielbild. Verpackung war nur ein Tütchen statt OVP, etwas seltsam. Sonst aber alles ok, bin super zufrieden. Danke Optics Spot:)

Fits after filing

A genuine, high-quality product. The rear sight mount is too wide. I had to have it professionally filed down. After filing, it fits the rear sight. After that, installing the collimator is a simple matter. The communication with the store is excellent. We reached a fantastic agreement. Thank you very much for the good and friendly communication. I recommend this store and the products it offers.

Ich bin sehr zufrieden mit dem Osight C

Ich bin sehr zufrieden mit dem Osight C. Das Absehen ist klar und superschnell im Ziel. Der Lieferumfang ist super. Passende Schrauben für alle möglichen Montageplatten sind dabei. Ich habe jetzt 2 Pistolen mit der Optik ausgestattet plus die zugehörigen Wechselsysteme. Für meinen S&W 686 plane ich das ebenso. Die Augen erkennen Kimme und Korn nicht mehr so gut. Die Gleitsichtbrille macht es nicht leichter. Mit dem Osight C bin ich wieder treffsicher im Ziel. Nun macht mir Kurzwaffe auch wieder Spaß.

Excellent product at a great price.

The plate is perfect, solid, and fits perfectly with the OR slide of the CZ Shadow 2. Unlike the same item produced by a well-known Italian manufacturer, it does not require dots to be inserted for coupling with the red dot because they are already part of the structure. The price is also significantly more competitive and shipping times are also reasonable.

CZ Target

Plate worked great so far. You’ll probably need an angled shim to zero in your red dot. Seems to be common with CZ.

Sro mount

This mounts is as described. Came with all the screws needed to mount on the slide and to mount the optic. Took about 2 weeks to get to me after submitting the order. Was shipped from the Netherlands. There were no additional fees ( tariff, customs or tax) up arrival.

Works great and fits nice

Excellent Quality Plate

I've had some adapter plates for my other pistols, but this one was a direct Glock MOS to Holosun mount and very low profile. It fit tight but perfectly and the machining is clean. Very pleased with this purchase.

RMR plate m9a4

Plate fit perfectly. Was able to install my infitac thermal dot with no problems.

Exactly as advertised

Was a little concerned when I saw it going through customs but it is exactly what I wanted and needed. Wasn’t able to find it anywhere else so I was relieved when this arrived.

Excellent to deal with

I tried to get information about this product from other suppliers but no one could give me a definite response, these guys were awesome and very professional.
The product was exactly what was discussed and fit.
Will definitely purchase from here again.
