Out of Stock
i have been using this MR5 for more than 9 years, i have used almost 10%, will this oil be expired or not? since i am using it for 9 years. can i still use it? thanks for reply.
The oil has no expiration date. It is good.
I've used this for years and I'm getting low so I just got another bottle. My last is Beeman No. 5 and is pretty dark in color as this Air Venturi MP-5 is in the photo but this new bottle is very light tan in color. It's not sealed, just wonder if I got a good bottle or is it mostly oil?
Is this safe to use on firearms?
I've been using it on them for decades. It's more for rust prevention than anything, which includes cleaning off finger prints. It also makes a pretty nice bore cleaner. Good stuff imo.
can I use it to clean my disco 22 without ruining the o ring on the bolt??
Yes, as long as you are careful when using it, it shouldn't be a problem
