RS parts compatibility chart

Postby silencery on Fri Oct 19, 2007 4:38 am

Being located in the US and lucky enough to have easy access to RS parts, I decided to take my mic and compile a compatibility list along with dimensions for our global PTW brethren.  I hope this will come in useful for some people. 

Contribute if you'd like; I don't see myself having a lot of time to maintain this data if people add info, so please feel free to copy the chart if you need to. All RS parts used in my measurements are milspec DPMS.  Systema numbers are taken from my Gen3 SCK.  YMMV.

Edit:
I've moved this chart to a publicly-editable spreadsheet on Google Docs to make it easier to read and update:

Nice chart.  On first glance I can add:
Take Down Detent Spring (Front & Rear)  N and Y

It is a much stronger spring for RS.  It can work but I had to cut about 1/3 off and still it's very strong.  I can't push the rear take down pin out with my thumb any more.

Another one..  Front sight taper pin... If you're really lucky the holes will line up.  In my case not even close so I tapped the holes and use grub screws.  I think this is the same with RS anyway, the front sight holes being drilled for the barrel it's mounted on. (Or so I was told by a RS gunsmith)

SBranson23,

Thanks for the tip.  That's kinda dependent on the sight base then isn't it?   Or are the taper pin sizes different between the RS version and the PTWs?

After several barrel swaps, the PTW taper pins became quite loose with the 2mm grub screw underneath doing all the work of keeping the sight secure.  The RS taper pins are larger and are very tight to install on the PTW sight base.    Further, when installing a RS front sight on a ptw barrel, the holes for the taper pins did not line up with the notches on the ptw barrel.  The holes for the taper pins are usually drilled to match the barrel they are going on and are seemingly not standardized.
So really, to add to your list, 

Front Sight Base - RS may need modification if holes do not line up with the grooves on the barrel.

Front Sight Taper pin.  PTW - 3.00mm diameter     RS - 3.19mm diameter

Thanks again sbranson.  Updated.

@ Doff,

I don't intend to let this thread die, but I won't always be around to maintain it since I'm only on these boards intermittently when I have time.  I hope someone can add it as a sticky or something.
