I have shot a Colt AR15 National Match HBAR since 1993. Not once in over 3,000 rounds have I even had a jam. Now Colt might have declined since then, I couldn't say, but based on my experience with that rifle, I would have to see considerable proof that they have problems, before I would bad mouth them.
LWRC I believe just got a big contract to supply 6.8 mm AR' type weapons to Saudi Arabia. It is the biggest foreign contract of its kind ever. That makes them very attractive to buy out. Also, this might be the start of a type standardization of a piston system in AR type rifles. If Colt adopts LWRC's system in widespread usage, It may eventually become an industry standard. Then you could build piston type AR's like you build DI AR's, mix and match.
