Guntec USA AR-308 Extended Takedown Pin Set

These pins do what they're supposed to do. The fit is perfect; no slop, but not too tight. I like extended pins because I do a lot of cold weather shooting and hunting outdoors and usually wear gloves, and being able to easily grip the takedown pin is a must. I usually use YHM pins in my AR15 builds, but they don't make a set for the AR10 platform and I'm building a Creedmoor precision rifle. These stick out a bit further than the YHM pins and aren't as clean looking, but they'll do the job just fine. When you factor in cost, these are the best pins I've found for the AR10 platform.

As a Vet (USMC, 01-06) the one thing i hated about the m16 was the takedown pins. I mean, they're good in that they function as designed, but they aren't perfect. OEM pins require the user to push from one side before being able to grab and pull from the other. These pins (obviously) allow the user to just grab and pull, which is what i think they always should have been. the knob doesn't protrude very far and they work perfectly. I have this set on my ar10 and the other set on my ar15. i recommend rounding off the points on your detent pins before installing. the detents are holes rather than divots and if your detent pin is too pointy it can get caught and lock your pin in place.

So they seem decent and all, but these do not fit a PSA AR-10 in 308. The rear take down pin is too long on the "far" side that should be flush. The side with the knurled end to pull on, it does not fit flush to the receiver, which prevents it from catching the pin, so it doesn't lock into place. The front/pivot pin seems to be the right length, but i didn't bother installing it since the takedown pin wasn't going to work. Will have to find a different set.

I like the idea of these pins and the idea of ease they are made for, but they do not pull easy and still need to be popped out before you can pull them out by the extended section. I would not recommend these pins to anyone and for those that have given them a good review, they must not have tried them out before leaving their thoughts about the item. I might just have a bad set, but it feels like the detent is going into the locking hole to far on both pins and not able to be popped out easily.
