It's never too late

. That's exactly what I did, I eneded up purchasing a used Thureon here on the EE and saved a fair bit. Now that I have it, I will say it is superior in every possible way. I like how the lower receiver uses take down pins instead of screws. Simple no tool required disassembly for complete cleaning. Uses AR trigger group. Has comercial spec buffer tube and Pistol grip making it AR furniture compatible. Monolithic upper. Lots of rail from the factory.
My only complaints are it doesn't have last round hold open and that I didn't get it sooner.
