It's called an accu-wedge, something like that. It tightens the fit between the upper and lower receiver. I too bought a New Bushmaster recently, it was the DCM Comp. It was loose as well. I sent it back to them, a few weeks later it was acceptably tight. If it's new and I'd send it back, have them fix it. Don't use the wedge to fix something that should not be loose as a goose from the factory. :)

How loose is acceptably loose? I have a month old bushy and it has a small amount of play between the upper and lower but there seemed to be no problem at the range. Could it worsen( is that a word) over time?

Some fit tight, some fit loose. Use one of them Accu Wedges if you would like. I myself do not mind a little slop between my uppers and lowers.

Acuwedge works great...it can work too good and you will have a hard time pushing out your take-down pin. Good luck...its the only thing out there that works.

IMHO, i think this is a scam... my m16 in basic was shakin, rattlin and rollin and I still shot expert. My colt has some play, my BM has some play...
again, IMHO, i think that hitting a man shaped target at 300m is more importaint than 1/4in hole at 100yds.... but to each his/her own... |

Even with the Accuwedge you will probably still have looseness at the front. One of my DPMS rifles is that way. I got some of those sticky mylar things that go around punched holes in paper that goes into ring binders to keep them from tearing out. the hole is .25" and I just trimmed it so it would fit on the inside of one of the "ears" for the front pin. One piece shimmed it nicely and now it's nice and tight. Avery Label calls them "gummed reinforcements".

NO, its not a scam. It's true (in theory) that the rifle should be accurate either way. HOWEVER, The accuwedge WILL prolong the life of the weapon. Here is why. If you start-out with a rattly rifle, the shock from firing it WILL BE MAGNIFIED between the upper and lower. A loose fit between the upper and lower will be worsened due to tolerances becoming way out of spec. If you have a rock-solid fit (or accuwedged) the shock is dispersed evenly because there is no slop to make the shock worse. Accuwedge...nothing to with accuracy, a lot to do with longevity. |

What about the Expandable Tensioning Pin that I see Bushmaster has in their catalog? This thing costs $35 so i'm not even considering this just curious.

The Tension pin thing is a great idea, but then I think you lose the ability to take your rifle apart without a hex-key. And one guy mentioned that after several takedowns he had inadvertently scratched and messed up the pin hole, etc, etc.
If it really feels -not right- send it back and have the manufacturer fix it, as mentioned above, and after that get an Accu-Wedge. It's cheap, tightens up your rear pin (you can use a bullet to push it out in the field) and won't hurt anything. |
