Most Helpful Positive Review Perfect fit.
These pins fit perfectly. If you are using a drop in trigger for your 15-22 theses are a must. Mil-spec pins sit recessed and tend to be loose with with my drop in trigger. The polymer lower is a bit thicker so the screws on regular anti walk pins were bottoming on tbe lower receiver. Great price and perfect fit and function.

Good but not Fantastic

by YankeeBluejeans, Verified Owner from MN, United States Written on June 21, 2024
This definitely works for what it's designed to do but my sample had two issues. First, one pin was slightly longer (or shorter) than the other. Second, one of the pins didn't allow the screws to tighten flush against the pin shaft.I think the threads were a little boogered up. I did chase the threads but it might be a depth issue.

They work and I wouldn't notice if I didn't install them myself. Otherwise, it's a 5-star product.

Not just for MP 15-22s

by J.S.T., Verified Owner from CA, United States Written on February 20, 2024
IF you have a lower that is wide at the trigger pins,like some ar10s, then these will save the build. A hair over 1 inch long. Perfect if you need it. Also has TORX screws that are 300% more resistant to rounding out than Allen heads. And they are very long. Very well thought out. Not missing a single detail. Very inexpensive.
Pros:
  • Torx fasteners,over 1 inch long (bareley)
Cons:
  • None
Best Used for:
  • Plastic 22 lowers and LARGE frame AR-10s
Would recommend: Yes

Perfect Works as described

by cjk, Verified Owner from WA, United States Written on April 13, 2023
Got these installed and they are great quality material. As a 15-22 lower is polymer it obviously will have lower tolerances so adding these was a great help when installing a new drop in trigger. I would highly suggest going with this product if you have a 15-22 and want to add a drop in trigger. Even if the trigger comes with anti walk pins you will want these as they are specific to the lower.
Pros:
  • Price
  • Quality
  • Ease of insallation
  • Install Time
Cons:
  • None

Junk screws

by Kingmanaz, Verified Owner from OR, United States Written on July 16, 2022
screw broke off in the end somehow on install, waste of money. These could have been useful if they spent 10 cents extra on better screws. Pretty useless when it breaks off inside the pin. Pins were of the right size and would have worked great if the one aspect of it needed to function can be literally screwed up on install
Pros:
  • Serves a specific purpose
Cons:
  • Low quality
Would recommend: No

A must have for 15-22

by Rick 259, from CO, United States Written on April 22, 2022
This kit is Required for proper installation in a Smith & Wesson 15-22. Without it the trigger will be very loose. The 15-22 has a polymer lower(and upper)so the dimensions are a little bit different than a regular AR.
Pros:
  • Easy to install
Cons:
  • None
Best Used for:
  • General Purpose
Would recommend: Yes

Exactly As Advertised

by Christobo, from CA, United States Written on March 26, 2021
The Anti Walk Pins work great. I have over 700 rounds through my AR since installing, and the pins have not loosened at all. Very easy to install, and any tools needed are included with the kit. Good investment for your AR style rifle.
Pros:
  • Work great
Cons:
  • None
Best Used for:
  • AR platfrorm 15
Would recommend: Yes

Solid Pin Set

by JustAsGood, from CA, United States Written on February 13, 2021
Installed for my Larue MBT-2S and these worked like a charm. Came oiled from the factory and with 2 hex keys for installation that look less than 5 minutes. CMC also has amazing customer service if you lose a screw or anything call them ASAP and they will most likely send another set no questions asked.
