Lining Up Rails???

[jtallen83]

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.

Can I have a side view? Does it use a standard barrel nut?

[jtallen83]

 

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...... :(

Did the hand guard turn when you tightened that hand guard nut up or did you get this upper complete ?

Wow...never seen that before.

 

How about you Rene?

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 ???

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.

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

  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 .

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>

This is how I align my rails when I tighten them up.

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]

I use a long riser to bridge the gap then tighten everything up to spec. Always worked for me.

[jtallen83]

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...........

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]

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 .

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]

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.

It all comes down to whatever you're most comfortable with.
