LMT is a top tier manufacturer that some argue to be equal to (or superior to) KAC. Accordingly, I do not believe there will be many products that are comparable in terms of engineering, quality of manufacture, or quality of materials.
2024 marks my 40th year of owning, building, shooting (informal, competition, and professional classes) AR15s. In those years I've owned virtually everything, and am blessed in that I can afford any "brand" I want. Having said that, for my money Colt and LMT get the nod for DI. In the piston market there are some good options like HK (if you don't mind the non-chrome bore), Caracal and PWS (if you don't mind nitride bores) and LMT (if you appreciate chrome bores, quick change barrels and monolithic uppers).
As astute reader will not the attributes ascribed to the LMT.
