Use of Loctite and set screws for front sight installation:Our very first Mini 14 front sights were pinned to the barrel factory pin location, and our customers had problems ordering because of the many different models and barrel / pin locations from Ruger and pin installation was a problem for many customers and it also required more machining driving the price up. To make the installation easier without sacrificing the integrity of the installation, we set out to find a better method. We ended up talking to Henkle Corporation, the parent company of Loctite. We explained what we were doing and their top lab technicians told us that Loctite 262 in combination with 8-32 set screws would be more than sufficient. There is no force directly agaisnt the sight!. Still a little skeptical, we tried it and found they were right ! After hundreds of test rounds through different guns, shooting until the target could no longer be seen due to mirage effect from heat exceeding 270* F, we then tried to remove the sight and found we had to use a torch on every gun tested and heat the sights to well above 450* F to remove the sights and even then we had to use vise grips. Then we upgraded to the new Loctite 263, even better! We understand some customers are leary of this method, and we were also, then we learned that modern chemistry has come a long way and made great advances and in the field of this kind of product we felt Loctite is the best. We have sold hundreds of Avenger sights nationwide and recently many of the new AV2 sights all using Loctite and cup point set screws and the single complaint we had so far was one customer who wanted to remove his Avenger sight, and literally destroyed in trying to. We gave him a new one. Loctite 263 is supplied with every one of our front sights and it has an operating temperature of 550* F, and is truly amazing. Yes it is a thread locker, but again, we were advised to use it on barrels by Henkle Technicians and it has been a great product and when installed correctly, i.e. clean surfaces and proper cure time, we stand behind this method. We also tested this method on a .308 bolt action rifle and again fired it until too hot to see the target and it held up perfectly. This method is safe and secure or we would not use it! We understand it is not an industry standard for sight installation, yet, however we have heard many success stories other than our's and also, one of our competitors selling an all aluminum front sight / brake combo has had at least one of their products come off and fly downrange due to heat expansion. We take this very seriously and your safety is number one to us. Feel free to do your own research on this amazing product. One more thing, some customers say that the pin method makes it easier to align the front sight to the rear sight / bore centerline, and it does get the sight close, however we have found there are many ways that are as easy or easier to align our sights, the best is using a simple cartridge or muzzle laser which we are selling at almost cost, but the majority of shooters already own these lasers for setting scope zero, and it makes the installation a breeze.
