I am building a 11.5" sbr w/ a2 flash suppressor and an ubr stock need to know what the oal will be.  

Don't have the stock yet to measure it. Thanks.

An SBR with a 11.5" barrel (flash hider does not matter unless it is permanently attached) and a new Colt collapsable stock is 30.5" OA. It is measured with the stock fully extended.

So find out if the LOP of a UBR is different than a Colt, when extended. If it is, add/subtract the difference to 30.5".

my 10" barrelled UBR SBR measures 28 5/8"  so add 1.5"  and you have 30 1/8" OAL
