ninemmbill Posted January 13, 2010 Share Posted January 13, 2010 So I need to mount a front sight on my AR with a Vtac handguard installed looking like this: Will this do it? It this part number right JPTR-FS It looks like it mounts on the front two hex head screws, but i'm not 100% sure, they are small screws. Thanks in advance.

Jesse Tischauser Posted January 13, 2010 Share Posted January 13, 2010 (edited) That looks like the rails that mount to the VTAC handguard. I didn't look up the part number so to be 100% sure you could call or email JP. Thier customer service is top notch!

ninemmbill Posted January 13, 2010 Author Share Posted January 13, 2010 I may have to call JP, it's just that I generally trust info from this forum even more than customer service at most places. Link to comment Share on other sites More sharing options...
MikeFoley Posted January 13, 2010 Share Posted January 13, 2010 OK, you can't used the part you reference, it is for use with the slots on the handguard, not the top. You can use any of the following parts though, depending on whether you want the rail to extend all the way from the receiver or just under the sight, and what length your handguard is. JPTR-R, the full length that runs from the reciever to the forward most screw hole on rifle length handguards, JPTR-M, the mid-length JPTR-C, the carbine You can use all of them on the rifle length handguard, the carbine and midlength on a midlength, and only the carbine on the carbine. Measure your handguard and see if it is 12", 9", or 7". If you have questions, you can call me at 800-387-4045. Thanks, Mike Link to comment Share on other sites More sharing options...

I tried without asking and you can't get it to work, even if the slot was correct the gas block gets in the way. Link to comment Share on other sites More sharing options...
tk4 Posted January 18, 2010 Share Posted January 18, 2010 Yes, I have that part on my vtac handguard for mounting a front sight. No need for the full length top rail if you just want to mount a front sight. I did double check the part # at jprifles.com. Link to comment Share on other sites More sharing options...
ninemmbill Posted January 18, 2010 Author Share Posted January 18, 2010 Thanks for the input. I did call JP to confirmed part numbers and order. I will post pics once they arrive. Link to comment Share on other sites More sharing options...
ninemmbill Posted February 4, 2010 Author Share Posted February 4, 2010 Just posting a follow-up. After contacting JP, it turns out JPTR-FS is the correct part. After installing it, the Magpul MBUS sights mounted up perfect. Link to comment Share on other sites More sharing options...
