@@dave_bobThe Armaspec? The 9mm version says it's only 6.4oz. equivalent (total weight of 9.5 includes not-reciprocating parts). Too light for most modern bolts to hit a 22oz. total weight goal. It may function in a 9mm but I wouldn't use it.
@@Blowback9 Yes that's the one, they claim actual weight is 9.5 oz, still might be a little light with the weight taken out of the bolt for function. I may try it out and see. I'm also going to try the tungsten pinewood derby weights for a carbine length GRS. I'm retired and have a machine shop .
@@dave_bob Must be nice to have a machine shop at your disposal! Just to be clear; the 9.5oz is not the weight to use in the reciprocating mass calculation (bolt+buffer mass). We need to use the equivalent mass - 6.4oz., then add the weight of the bolt with the bolt mass removed - usually 12oz. That's only 18.4oz. Very light! The mass of the guide rod parts and spring on the unit don't count, since that mass isn't adding to the bolt's inertia resistance to opening the breach.
@@dave_bob "Actual" weight is how much weight it adds to the gun. "Equivalent" weight is how much weight it adds to the bolt. "Equivalent" to using a 6.4oz. buffer. However, it's necessary to remove the 2.5oz.-ish bolt weight to use it. So it may really only act like a 3.9oz. buffer. That's not a little light, that's extremely light.

Great video and great point about gloves! I'm not concerned about the cleaners as much as I am about the lead in firing residue, trying to keep those heavy metal levels as low as possible.
Firearms need to be cleaned. You need to have a schedule that works for you and your weapons. My range toys are not going to be pristine, however they are going to work when the trigger is pulled.
