If you’re a Mosin Nagant owner then you probably how much of a pain in the ass the cocking knob safety is. If you’re not a Mosin owner let me explain, it’s a pain in the ass to use. So much so that most people probably don’t even use it, which isn’t good firearms safety.
The folks at Brass Stacker who make an awesome Mosin Nagant scope mounting kit also makes this nifty pull ring that makes it much easier to actually use the Mosin’s safety. It’s made of brass so it won’t mare your Mosin Nagant and it installs without any special tools. Check them out online at Amazon.com.
