    Dropping hammer on separated lower

    Hello,

    I'm new here, and as such I've been voraciously going through the threads. Very knowledgeable bunch of folks.

    As the title indicates, one topic that caught my attention is dropping the hammer on a separated lower. Some say it's bad, some say it doesn't matter, but the threads I have read didn't seem to have "proof" other than the usual "that's not good, ask me how I know" and then fail to follow through when asked.

    So I ask it here. Is it really that bad? What are your real world experiences? The reason I'm skeptical is because on an empty magazine, at least in my mind, you have the force of the action spring and the inertia of the BCG + buffer (H2 in my case) slamming against the bolt catch all the time. I haven't been in school in a while, but I'm thinking there's more force and inertia behind a BCG and buffer in full return than a hammer with a fraction of the weight. Do I have this wrong?

    As far as my own experience goes, I did it regularly on a third-world-manufactured M16 lower. I didn't dry fire on it, but I certainly did it once or twice every time I cleaned it. It's an A1, and between my Dad and me it's been "dry fired" on a separated lower quite a few times.

    Thanks for the input guys. If this has been discussed before please point me to the existing thread and Mods please close. I searched for a while but my Google-fu could be off.

    My hammer only drops when I shoot it... are you going to be sitting on the couch or at the range "practicing" with this?

    My question is why? Im sure its not good, its not gonna hurt the hammer itself, Im pretty sure it would affect the lower though.

    Has it happened before? Yes.

    Do I sit around and keep dropping the hammer while separated? No.

    The parts getting "slammed" into like youre refferring to, the buffer BCG Etc.. are DESIGNED for that. The aluminum magwell thats getting the shit beat out of it everytime you drop your hammer isnt. STOP IT!

    You run the risk of damaging your lower.
    Possibly cracking the thin aluminum between the fire control pocket and the bolt catch cut out.

    With the upper installed, the hammer falls on the firing pin as it is supposed to; not the bolt catch.

    When you pull the trigger on the lower only, the bolt catch takes the brunt of the hammer blow....it is not designed to be repeatedly (or at all, even) whacked with the hammer. I don't have any real world experience (and I will never gain it either, as when I dryfire stripped I always let the hammer hit my hand instead), but I do have enough mechanical sympathy to see this is an extremely unwise idea as it beats the shit out of the bolt catch and the lower.

    As regards your thoughts on the BCG.....can't quite see what you mean as that doesn't slam the bolt hold either; its the barrel extension that dictates where/how the bolt seats, and by extension, the carrier.

    That hollow sound the aluminum makes when a heavy piece of steel hits it should be a dead giveaway.

    If you want to give us a "how many licks does it take to get to the tootsie roll center" test...by all means

    It's a no-go for exactly the same reason that you wouldn't want to **** a cheese grater - because sooner or later, something very important will get damaged.

    But doesn't the hammer rest/hit the bolt catch when it comes down, instead of directly on the receiver?

    And before everyone gets their panties in a twist, I didn't say I would be dry firing with a separated lower. It's a discussion, that's all.

    The comparison I was trying to make was the force of the BCG+Buffer+spring return against the bolt catch vs hammer+hammer spring against the bolt catch when the upper is removed.

    Again, just a discussion. If you can't keep your responses civil, take it somewhere else.

    I just explained it....its a moot point because it doesn't happen when the upper is installed. Have a read around here....plenty of posts explaining how it all works.
