jtallen83 Posted July 6, 2014 Report Posted July 6, 2014 Got my new ArmaLite upper and Spikes lower put together today. No real issues assembling the lower but when I shouldered the weapon for the first time I noticed the rails on the handguard and receiver do not line up :rant2: I don't have a vise, blocks, or anything else for tools that doesn't fit in my range bag. Is there an easy fix for this or am I sending it back to ArmaLite to line them up? <dontknow> Sorry about the poor pictures, couldn't get everything in focus.
edgecrusher Posted July 7, 2014 Report Posted July 7, 2014 Can I have a side view? Does it use a standard barrel nut?
jtallen83 Posted July 7, 2014 Author Report Posted July 7, 2014 (edited) I'm assuming this is the standard nut. I read through the ArmaLite tech notes and watched a couple videos but they were no help...... :( Edited July 7, 2014 by jtallen83
survivalshop Posted July 7, 2014 Report Posted July 7, 2014 Did the hand guard turn when you tightened that hand guard nut up or did you get this upper complete ?
planeflyer21 Posted July 7, 2014 Report Posted July 7, 2014 Wow...never seen that before. How about you Rene?
jtallen83 Posted July 7, 2014 Author Report Posted July 7, 2014 Did the hand guard turn when you tightened that hand guard nut up or did you get this upper complete ? The upper came complete from ArmaLite. If I could find some directions on how this handguard was installed I may attempt some reverse engineering to fix it,if I have the tools, but nothing I'm finding says a word about how the rails are lined up. It was on sale but they didn't say a word about seconds or anything ???
blue109 Posted July 7, 2014 Report Posted July 7, 2014 my PRI rail looked like that when I first installed it. the tube has 2 studs that use the holes in the barrel nut to index. I thought I had the barrel nut aligned until I put the tube on and saw it was off a tiny bit. took some back-and-forth to get it just right. easy fix if you have the tools. in your case, I see some fedex in your future.
Rsquared Posted July 7, 2014 Report Posted July 7, 2014 Use a strap wrench on that outer nut. Loosen it up a bit, and you'll be able to line her up.
washguy Posted July 7, 2014 Report Posted July 7, 2014 Use a strap wrench on that outer nut. Loosen it up a bit, and you'll be able to line her up. thats what im thinkin too :) Wash
survivalshop Posted July 7, 2014 Report Posted July 7, 2014 (edited) I would call or email Amilite , that should never made it past inspection or could have been bumped in shipping . They will tell you how or what to do with it . I agree, the hand guard tube is out of alignment , but not sure if just loosening the cinch nut, if it will align correctly or if there is some kind of pin system that was also mentioned .

j.peace Posted July 7, 2014 Report Posted July 7, 2014 Have a similar rail with same but. Loosen nut with strap wrench. Straighten rail and re tigten but. Issue solved
unforgiven Posted July 7, 2014 Report Posted July 7, 2014 Wow...never seen that before. How about you Rene? No,but the strap wrench idea is sound.Unless you have a 1 pc. scope mount or Eotech to bridge the 2 rails and tighten it up for alignment.The good news is the direction it has to go will increase thightness. :)) All you guys here forgot more about firarms then I'll ever know. <dontknow>
392heminut Posted July 8, 2014 Report Posted July 8, 2014 Unless you have a 1 pc. scope mount or Eotech to bridge the 2 rails and tighten it up for alignment. This is how I align my rails when I tighten them up.
98Z5V Posted July 8, 2014 Report Posted July 8, 2014 I use a long entended mount to bridge the gap. Lock down the long mount onto upper and rail (both), beat the barrel nut into submission. Done.
shibiwan Posted July 8, 2014 Report Posted July 8, 2014 I use a long riser to bridge the gap then tighten everything up to spec. Always worked for me.
jtallen83 Posted July 8, 2014 Author Report Posted July 8, 2014 I've got an extra ArmaLite scope mount with me, I'll give that a go. ArmaLite thought they would need it back, I just need to call a different extension...........
jtallen83 Posted July 8, 2014 Author Report Posted July 8, 2014 I use a long entended mount to bridge the gap. Lock down the long mount onto upper and rail (both), beat the barrel nut into submission. Done. When you say "beat it" would a small brass hammer do it? Should I try to protect the nut from the blows with something? I hate the idea of beating on a new rifle but then it might feel good..............
survivalshop Posted July 8, 2014 Report Posted July 8, 2014 This is what I use for installing & aligning upper rails . Problem is yours is already installed & you need to loosen the hand guard nut up to probably to re-align the rail .

Rsquared Posted July 8, 2014 Report Posted July 8, 2014 Don't beat on that thing. Use the same strap wrench to tighten it back up once it's aligned. And I agree. That shouldn't have left their factory like that. I guess everybody stumbles from time to time. But that doesn't make it any less annoying.
jtallen83 Posted July 8, 2014 Author Report Posted July 8, 2014 I'll try my strap wrench but I can't get any type of mount to bridge between them, the nut is in the way.......Looks like a trip back to ArmaLite may be best.
Rsquared Posted July 8, 2014 Report Posted July 8, 2014 It all comes down to whatever you're most comfortable with.
