I think the cause for the misfires is bolt bounce. I got no problem with any brand of ammo except armscor in which i have an occasional failure of the bolt to lock back & failure to strip an ammo from the mag. cyclic rate is greatly reduced. In my brother's 14.5" M4, i installed a lightened weight that is equivalent to H2 and it works fine even when using an armscor ammo. Both of our M4's are select fire & we've never experience a misfire or bolt bounce in full-auto (mine using only M193 & Prvi 55gr.).Quote:
so what's the difference between a 1 piece buffer weight and a 3 piece buffer weight?
was this the cause of the misfire?
heavy metal... yes. been looking for tungsten. can't find.
chime,
how did you make your buffer weights. very interested.
I would like to try up to H2. I think an H3 would be too much on a 14.5in
So what you're trying to tell me is a 1 piece weight will not matter? as compared to a 3 piece?
it took me months looking for tungsten rod but haven't found one. if ever you can find a tungsten, you're next problem would be machining it.Quote:

I made one using a TP design buffer and cut a several grooves (about 1.5mm width) into the 2 weights to lightened it & make it 4.6oz (130.4gms) overall weight or equivalent to H2. TP buffer is 5.3oz (150.2gms), By the way, my brods 14.5" barrel have a 0.061"dia gas port.Quote:

I got a FTF with light primer strike (maybe it is casued by bolt ounce) on every 3rd or 4th round using a single weight. I'm using a 2 piece.Quote:

chime,
there's no way stainless can be as heavy as an h2 or even h1 buffer weights.
so you're experiencing bounce right now? is it due to the 2 piece design of your buffer weight?
im not familiar with how the tony pascual buffer looks. have pix?
yup, you're right stainless steel cannot be as heavy as the original buffer weights (i tried that one also) , much more the tungsten weights but i didn't use a fabricated stainless steel as a replacement to the original M4 buffer weight. I fabricated the whole buffer assembly that differs to the design of the original M4 buffer. it looks like a hydraulic buffer.Quote:

I'm having a FTF with the 1-piece weight design and it is now fixed using a 2-piece weight design.Quote:

I'll be going home for lunch right now. I'll post a pic after a couple of hours.Quote:

I see so you have a heavy buffer housing. I think that's what's causing the problem.
I weight the whole buffer not the weights alone.Quote:

the design shows a reciprocating mass.
but won't the reciprocating mass get hit by the spring? thereby slowing them down?
if the moving mass doesn't reciprocate freely. It might not be as effective.
the original design has a free reciprocating mass.
I measure total weight. and weight of reciprocating mass
just an opinion.
