Optic Mounting Plate for Ruger 57/ Ruger 5.7 - Compatible with Trijicon RMR/SRO, Holosun HS407C/HS507C/HS508T, Riton X3 Tactix PRD, Swampox Kingslayer/Liberty/Justice, RD3-019 Stingray, ADE RD3-020 Raptor, RD3-022 Artemis, RD3-023 Valkyrie, RD3-029

Quality made for sure. This mounted without problem to my Ruger57 ready for my ADE Stringray on its way. I will post pictures with the final mount finished but as far as the mounting plate itself, great design, price, and durability. Fits like a glove.

Machined well, includes 4 level mounting screws and key. Packed well to prevent scratches. Once I get it mounted I'll update pics.

Solid optic plate that fits the Ruger 57 perfectly. Installation was quick and everything lined up just right. I really appreciate that the bolts already came with blue Loctite—it saves an extra step and gives me confidence that the optic will stay tight after range sessions. Overall a great value and very secure fit.

This mounting plate is a must-have if you want to run a red dot on the Ruger 57. Installation was straightforward—fit was snug with no play, and it lined up perfectly with my ADE Stingray red dot. The screws were the right length, and I didn’t need to do any extra filing or shimming. The machining looks clean and durable, and it holds zero after multiple trips to the range. Overall, it’s a well-made, reliable plate that does exactly what it’s supposed to do.

This mount fits the Ruger slide perfectly and seems to be a quality piece of gear. It came with all the needed mounting hardware and even included an Allen wrench to mount it. I did need my own Allen wrench to remove the tiny set screws in the factory holes, but most Allen sets will have those. The plate seems like durability will be good as well. Functionally the red dot I had on hand worked great and the sigh picture is plenty acceptable. Overall, if you want to put a red dot on your 57 then this is a good option. Make sure you have one that’s compatible though as there are a few different mounting styles out there.

The good- - Sturdy optics plate that fits well and does not shift under firing - Compatible with RMR footprint - Matches color and finish of Ruger 57 slide The bad - May possibly need your own screws for certain optics

This really seams to be a nicely made Optic Plate for the Ruger 57 Pistol. I know from reading different sites that you have to be careful with the total weight you have on the Ruger 57 when running a red dot optic on this pistol. I didn't get the total weight before I installed it but I will have to update that. But the Fit of this was on the dot I did have to get smaller screws for the install and it was a fast install after. I believe I found them in my other kits I have from other installs. But the install when very easily and the look is really nice. I have great back up speed shots when shooting with this. And it functions great with all the different ammo types I had on hand.

The screws already come half installed and with lock tight. Very impressed with that. For the price I expected rattling or loosening while shooting but not at all it held its place even trying to move it with my hands after installation it would move at all. It’s great quality and comes in the perfect size! This is a great pick for protection. It will hold its own in stressful situations. The value for the cost is great. I didn’t it to be made this well. It functions great, I’d give it a shot if you have a R57!

I bought this after getting a new Ruger 5.7 and realizing my old optics would not fit. This plate fit like a glove and locked the optic in place with no wiggle. Machined aluminum feels solid and light, and the footprint matched my pistol perfectly. Two things to note. First, the included screws work for Trijicon and the common Holosun models, but some other red dots may need different screws. Bring the sight to a local hardware store (my Ace also happens to be my local FFL dealer) if the supplied screws do not match. Second, with heavier RMR style sights you may need to run 40 grain ammo to keep reliable cycling. That is not the plate failing, that is a weight and cycling reality. For the price, it does exactly what it should: secure your red dot to your Ruger 5.7 and let you get back to shooting. If you own a different pistol or an uncommon footprint, this is not for you. Best bet - if you own the 5.7, get this optic plate and optics that are specifically meant to be used with a Ruger 5.7.

Looks like it does in the photo. Nice looking plate. Waiting for a part for my 57 to put it back together and it'll be nice to get an optic mounted.

This plate fit perfectly on my Ruger 5.7 and the Holosun 407c fit perfectly on the plate, no complaints. I have asked the seller what the particulars ion the screw size as I need shorter ones. It clearly states that you may need to source them which is fine, I just need to know what size the are so I can buy shorter ones
