Now I want a magpul ubr. However I need a carbine buffer and spring. But I can't find one. Where the heck do I find one?
HKMR223A3 in RAL8000
Already replaced the stock, flash hider
Removed the sling plate and added a Blue Force sling.
Optic: Trijicon Acog w/ RMR LED adjustable.
A trigger upgrade should follow shortly.
Did this rifle come from the factory with the ambi mag release? Just curious, as my HK MR556 did not...
