So yah, I downloaded this like a lot of other ppl and struggled like crazy with the original design.  it kinda sucked.. and I was determined to make it work cuz I know lots of avid shooters, including myself, who would benefit greatly from it.   Arthritis sucks! 

 

So anyhow, yah I made the base overall smaller and more compact, clearanced a few parts for easier operation and whatnot, eliminated the original plastic pegs, and converted it to a design that uses screws and heated inserts.    The coolest part is I modified it to fit 300BO.. whilst still maintaining its ability to feed 223/556 as well..  1 loader, multiple magazines!   

 

You'll need a few parts to do it right.   Your gonna need 4 inserts for M4 bolts.    and you'll need 8 small metric screws as well.  Button heads.    M4x12 and M4x16.   5 of each.  you'll have extras leftover.   The heated insert holes will be obvious.   they're big..  there's a few holes that will need pre-tapped and won't take a heated insert.   One of them is RIGHT ABOVE the mag release button area..  the other 4 are on the base.  (where you stick the base and 300base together..)   You'll also need a spring from a ball point pen (or equivalent) for making the PUSHER return easier.  ill have to get pics of that so folks can understand better.   a little grease on the linkage button and grabber won't hurt either.   

 

I also included printable mag release parts.. you can get a socket head bolt from the hardware store and make that work too if you want.  I suggest printing those parts at a super high resolution and solid infill.    Alternatively, you could buy metal ones… they're not to expensive.  

fit all parts and make sure they move smoothly before filling it up and attempting to load a mag.   check out how it feeds em and they drop down TIP first..  when you cycle the pusher, shove that sucker in ALL the say, and let it come back out.. you'll hear the shell DROP and smack the base.. thats your indication that you can PUSH the PUSHER towards your mag which will stuff the projectile into the mag.    I found that HOLDING the mag while pushing the pusher, makes for a good stable and reliable feed every time.    so far, the ones ive built for 223 have loaded quite a few mags with no major issues.   once in a while it'll flop a shell the wrong way and you can just shake it loose. 

hopefully everyone can get this one to work.  I did put some time into it.   enjoy.
