BLACK RAIN AR15 SAFETY LOCK

Does the job although over priced. Comes with zero instructions or documentation. No info on their website. Not hard to figure out though.

I have children and I have firearms. Therefore I take gun safety extremely seriously. And while I appreciate that many guns today come with locks and the NRA has many programs to give locks away for free, let's be honest they are cheap POS. I have a Black Rain Ordinance SPEC 15 (but it should work on all AR15's) and use this to lock up the chamber. A round may not go into the chamber, the bolt may not move, and the charging handle can only move about an inch before it hits the lock. It slides in perfectly and locks easily. I have a Vortex scope mounted above the ejection port and there is no interference. The thing I very much like about this is that a magazine can be in the gun and it can be locked. If SHTF, the rifle is ready to go with a single twist of a key and letting the bolt slam home. Less to fumble with when seconds count. Finally, I have a thing about buying American. While I can't say my firearms and accessories are 100% made in the USA, I'm easily over 90%. Very happy to buy this American made product.
