Tet - thanks
But I have no idea on how to do that
I love the URXII
They are out for civilian sales in post ban SR15 Match rifles, and Gov't orders for the SR16's.
'Mine' is a SR16 upper with 1:7 Douglas 'SPR type' profile midlength barrel, and the wonderful KAC flip front bayo lug.
Now I learned that putting a BOTB suppressor will ruin the KG (scratch it) coating on the barrel - oh well.
I have a similar MRP 16" - and like the URX better, as the FF M203A1 mount is more robust -IMHO- than the LMT clip on for the MRP. Similarily the MRP does nto allow for our BOTB suppressor to be affixed as they require the standard distance from the FSGB to FH.
Unlike TR

, I am a huge fan of the 16" bbl for general purpose issue - of course we have the AR10 MRS as well so I have no need of a longer range 5.56.
I plan on upgrading a few guns to URX's when possible.
