    I initially had the spacer installed with a carbine length spring and carbine length buffer. This would not allow the bolt to go back far enough to pick up the round to chamber. Once I removed the spacer it worked correctly. Only problem I have now is the spring doesn't have enough power to fully chamber the round. I fear that if I put a rifle length spring in it that this will not allow the bolt to go back far enough to pick up the round. The UBR 2 manual states that you aren't to run a rifle length spring in it.

    An A5 uses a rifle length spring. I don’t know what context the manual refers to by that statement.

    A rifle length spring with a carbine buffer will give the adequate space with the AR10 carrier.

    Excerpt from Magpul regarding UBR 2.0:

    "A carbine buffer and spring (M4 or SR-25 length) or A5 buffer and spring are required for use with the UBR and are not included.“

    You are right, the AR15 rifle length spring may be too long, but a 308 rifle length spring should be fine.

    Maybe my post wasn't clear (I said it was confusing!), but you have two options:

    1) Put the spacer back in, use an AR15 carbine springs, and get the short DPMS/SR25 308 carbine buffer: https://aeroprecisionusa.com/308-carbine-buffer.html

    or

    2) Leave the spacer out, use your AR15 carbine buffer, and get an Armalite AR10 pattern buffer spring (which is the same for AR10 rifles and carbines but is different from both AR15 rifle and carbine springs and not the same as the DPMS/SR25 carbine spring): https://www.rainierarms.com/armalite...buffer-spring/

    I recommend the latter.

    Pretty sure I'm building an AR-10. Looking for some advice.

    Picked up the Armalite spring from DSG Arms for $11.50 shipped. We'll see if that fixes me up.

    Rifle length spring arrived today and now it operates correctly. Now I just need an opportunity to shoot it.

    Undecided on glass and looking for suggestions. I run red dots and my recently acquired ACOG on other rifles. Don't own any high quality higher magnificaton optics.

    300 yards will be the typical distance that this setup gets used at.
