Most Helpful Positive Review Easy Install
This stock lock pin is very easy to install and is the quickest and probably cheapest way to turn your collapsible stock into a fixed/adjustable (with a tool) one, becoming compliant with the laws in CA. You will need a roll pin punch to punch out the pin holding the original stock pin in place. No drilling. No permanent modifications. Maintains original look. The stock can still be adjusted to desired length with an Allen key.

Works as promised but needs one longer screw

by Al, Verified Owner from NJ, United States Written on December 28, 2024
The pin works as advertised to fix a telescoping stock. For the B5 stock the screw wasn’t long enough to keep the adjustment lever in place but wasn’t a big deal since it would be only there for looks. Would be nice if they included an extra longer screw, but that can be easily bought at a hardware store. Overall much better than the more expensive alternatives or drilling the stock.
Pros:
  • Esae of use
Cons:
  • None
Best Used for:
  • stock pin

Simple replacement for stock adjustment pin

by Huey, Verified Owner from CA, United States Written on October 25, 2024
The hardest part was removing the roll pin from my original stock. I wish there was installation pictures, and I had to find a youtube video to figure out how this worked. I'm sure a trip to the hardware store could replicate this kit but you pay for the simplicity and it fit like it should without any permanent modifications to a B5 Bravo stock.
Pros:
  • Easy to install
Cons:
  • No instructions
Would recommend: Yes

Fixed rifle stock

by azezzo, Verified Owner from NY, United States Written on September 10, 2019
This was pretty simple to install, under 5 minutes even without instructions. Fixed a magpul moe adjustable stock to the buffer tube to make it ny compliant. You will need a drift pin, pair of needle nose pliers.

M4 style locking pin

by Pops, Verified Owner from CA, United States Written on November 10, 2017
I just just received the locking pin yesterday. If you live in Kaliornia this is a must have for your sporting rifle. Check out other Kalifornia compliant products from OpticsPlanit. The installation was totally simple. I've ordered several other products from OpticsPlanet and I'm very stisfied with everything. The customer service, when I've had to call was great. Thanks O.P

AIM Sports Inc AR/M4 Style Stock Locking Pin

by Dagon74, Verified Owner from CA, United States Written on October 12, 2017
Inexpensive way to lock your stock should you live in a restricted state. There is another product like this on that way over charges, close to $40 and only real difference is it also comes with a shorter bolt to work on thinner style stocks.Would give it 5 stars if it and a shorter bolt for battlelink style stocks.
Best Used for:
  • Commie state compliance
