AR-15 ANTI-WALK PINS Reviews & Ratings

Oversize pins hold hammer and trigger in precise alignment without the free play and camming action that prevents a clean and consistent trigger letoff. Moly impregnated to reduce friction. Hex-head screws locate pins to frame, eliminate the need for the hammer J spring. Installation may require reaming hammer for proper fit.

SPECS: Tool steel, moly coated. Small - .156" (3.9mm). Pack of two pins.

I could not find star hex wrenches to install them.

I would be nice if they provided star wrenches, or use regular hex screws.

Too long on a PSA lower.

As someone else stated in their review, the pins are too long. Installed on a PSA lower, noticeably too long. Will be returning them. Note: PSA AR15 COMPLETE MOE EPT WITH ADJUSTABLE BRACE LOWER, FDE - 5165448739

Too long

The pins are about 1mm longer than they should be so the screws do not fit flush against the receiver. The screws are likely to catch on things and would probably end up scratching me if I keep using them. I have an Aero Precision Lower and I highly doubt it's the lower that's out of spec.

Not for me

I have experienced pins walking out before & don't use standard pins anymore. Have used the "anti-rotation" type before with good results but decided to try these based on the lower comparative price. I am returning them. The screw heads did not sit flush against the sides of my cmmg lower. Not a huge deal, but I didn't like it. Have read another review where someone filled the gaps with washers they painted black but it wasn't worth the effort imo. In the description it says "eliminates the need for hammer j spring." It does not say "requires removal of" but it should. Maybe I should've read more reviews? Did not have a problem with the pre-applied loktite like others. Tried with psa ept trigger & it would not go thru hammer without removing j spring. I did not want to do this, so I ordered those "anti-rotation" pins instead. I think they're worth the higher price. JP makes great products & these pins may work for some but only speaking for myself, not what I was looking for.

Great idea but.....

The first set of these I installed quickly without any issues. Then I bought these and my expectations quickly sank. I didn't have to do anything to the pins. They slipped in place quite easily. My problem is, I believe, with the thread lock they put on the screws. The screws went about half way in and then became very difficult to install. The screw heads won't take the amount of torque required to tighten them properly. Also, it would help if they would either include the proper size wrench or at least state the correct size to be used. Leaving the loc-tite off may be a good place to start.
