2 piece handguard too long?

[EasyEJL]

I assembled (not in a vise, just hand tight) the barrel nut with delta ring on, and put the end cap + gas block on and did a test fit of the handguards. I got the UTG quadrail 2 piece since the price was right. Seems like its somewhere between 1/8 + 1/4 an inch too long to be able to work and i'm not sure what to do. I loosened the gas block, slid the end cap forwards and got it to work, but of course the gas block isn't lining up with the barrel hole anymore.

Any ideas?

the handguard measures 12" end to end, so apparently somehow the length from barrel nut to gas block is the problem. yay.

I put a set of the carbine size on a rifle for a buddy & didn't have a problem .

It had a std front sight on the barrel & I just replaced the Std carbine hanguards & tightened the bolts .

He was very happy with them & I thought they worked well.

What are you putting these on? Not mixing AR-10 gas system with a DPMS weapon are you?

I have a 2 piece rail like that on a regular AR. on mine you need to install the rear(barrel nut end) and then slip the front in(gas block end). Its oppisite of how ive always installed USGI handguards so it threw me at first. If you dont do it rear first it seems like its too long. Maybe give that a shot if you havnt already.

yep, the troy mrf rail (all I could find inexpensively in FDE is pretty damn sweet on it instead. can't wait to torque down the barrel nut + install it + gas block for good! Extra happy the FDE is a perfect match with the duracoat magpul FDE.
