Nice, Solid (USA!) Pic Rail - 5 & 7 Slot Photos Reversed

by ToolGuy, Verified Owner from PA, United States Written on August 13, 2024
Nice poly rails, well made in USA!
After ordering several 7 slot rails to mount folding handguard pistol grips, I realized a 5 slot photo is shown for the 7 slot listing, and vice-versa. Fortunately OP sent 7 slot rails, which is what the description and part # reflected.
These are not hard plastic as I expected, they have a bit of flex in them, sort of like hard rubber. This is probably a positive, as they should absorb impact better without breaking. And aftet the two M-Lock fittings are tightened, they feel nice and solid.
Overall, a well made, solid little rail for a great price.

Exactly what I wanted

by TDJ22, Verified Owner from FL, United States Written on December 28, 2023
Very well made, seems like it'll take a beating. I attached it under the muzzle of my ar to mount a streamlight. It works great and very affordable. Thank you Optics Planet!

This worked perfect for adding a flash light on my AR. Nicely made. Good quality and easy to mount. Looks good too and doesn't look like an add on. Has a good finish which matches the AR. Very durable and solid mount for my flash light.

  • fits good
Cons:
  • None

Did exactly what I needed it to do. Good quality with zero issues. I got the smaller version to put on my Angstadt arms udp 9mm with a 5.5 inch hand guard. Fit was perfect. My light with picatinny rail mounted just fine.
Pros:
  • Ease Of Use
Cons:
  • None

Great product

by Blackout BOO, from AR, United States Written on June 1, 2023
Easy to install on my em lock forearm and allowed me picatinny space to mount other needed items on my weapon. Light, bipod, could be mounted far enough forward to help clear brass catcher! I would definitely recommend for someone adding equipment to their weapon.
Pros:
  • Can get different lengths to meet your needs
Cons:
  • None for me
Best Used for:
  • Anything requiring picatinny mount rail.
Would recommend: Yes
