Reviews & Ratings for Tacfire MAR108 AR15 ANTI-WALK PIN SET — 8 reviews — Page 1

Works as designed, screws were pretty located and once there on you don't have to worry about the screws coming loose or the pins coming out. Install took less than a minute

Pretty sure this works on AR-10 as well but this was put on AR-15. They work but do not plan on removing them often. Had to swap an insert trigger assembly to another build and its Spike Industries trigger to the build these are on. One of the allen holes are stripping. I did not tighten down really as it was a build in progress and not near completion till recently. So maybe they can build them out of a stainless steel instead for a few dollars more. Lightweight is great unless it compromises the ability to remove and re-install for maintenance reasons.

Bought this as my trigger pin kept walking out. Probably a manufacture defect, but with these bad boys in I have no concerns. Rapid fired 60 rounds through it just to give it a quick test. This should be the default pins in my opinion.

These pins do exactly what they are supposed to do in my Anderson lower. Just be aware that if you have a polymer lower like the OmniMaxx that you need longer pins than this. I have one of those sitting around as well and these pins do not meet the length needed for it.

Seems to be well made. Nicely finished. No rough edges or mars in the surface. Fit smoothly on my lower build. Matches well with my extended take down and pivot pins, as well as the mag catch assembly and bolt catch. Looks like everything will produce an excellent finished product. It was very helpful to have the install tools included, if you did not have AR build tools. I am not sure if these are really necessary? In the hundreds of thousands of rounds I've put through various AR's, (many were well worn full-auto military rifles) I've never had a pin walk out of my receiver. They will give you an extra measure of confidence, and if it helps you sleep at night, go for it. I would be more inclined to buy anti-rotation pins for a "select-fire" 16, so that the super valuable lower would suffer less wear and tear. The ONLY reason that I cannot give this 5 stars is that after 2-1/2 months I am still waiting for an upper which was estimated to be shipped 6 weeks ago, and I cannot complete my build and test fire the finished product until I receive the upper.

Inexpensive and works well with my AR trigger. Install was easy and did not require removal of this particular lower's somewhat complicated trigger. Got a less than 200 rounds through it but loctite is holding.
