Great for new build or replacement on current ar - Battle Arms Development AR-15/AR-10 Enhanced Pivot/Takedown Pin Set

I purchased a set of these for my AR several years ago and was extremely satisfied! So much so, I have used them on all my builds since. Install as a replacement on existing AR is not bad at all. However, instead of using instructions, search on youtube! You can find GREAT videos that show how to replace your pins on a current weapon WITHOUT LOOSENING THE CASTLE NUT! Not only is it easier but also does not compromise where you currently have a properly staked castle nut. On a new build, it is just the same as standard pins to install. The extra little bit of length does not cause any problems at all but, sure makes take down much easier. I recommend the product! You will be glad you spent this little bit of money!
