I have seen the posts for the Sirs rail system but I have the DPMS 4 rail handguard and am having a tough time getting the vertical grip on it. I was thinking I need to break out the file. Has anyone had to do this on one of the DPMS rail systems? If so, what exactly did you file to get it to fit? Any help is greatly appreciated.

Also interested to find out.

I think the DPMS 4-rail is the same as the Yankee Hill Machine deal.
And from what I heard, the TD VFG requires a wee modification to hang on the not-exactly mil-spec Yankee Hill forearm.

Ya heard?

I got it on. I lubed it up real well and tapped it on with a small hammer. Once the rail shaved off the small amount of extra plastic that was holding it back it slid right down with a little help from the hammer. Did not take much force just very light taps. It is on there very tight and has no play at all. Not sure it will come back off without the use of the same method but at least it is on there nice and tight.

You mentioned the SIR issue, which I had. I ordered the TD Sir rail along with my Vert GRip and was still very tight.

It's rock solid though!

I'm starting to wonder about TD and the mil spec claim. The replacment TD vertical grip on my M73 is slightly loose (not as bad a sthe first one that I sent back), while the TD rail panels fit like a glove. Does TD have different standards for their various products? BTW, I'm not bashing TD, I now have the TD VG, BG and rail covers (all from you, thanks for the great service)!

I guess I figured that since they both slide on they'd have similar specs on the "V" prtion of the Picatinny cut. Thanks for the quick response and again, thanks for everything! I hope to have a pic of my complete G&R AR soon Chris
