  1. Mark Retzlaff (verified owner)

    LMT is top notch equipment, but even more important is the customer service from Big Tex Ord. Fast and reasonable shipping costs in these days of increased shipping costs! Bg Tex had the best prices on very hard to find LMT products that are normally out of stock everywhere.

  2. C.Burroughs (verified owner)

    Had a LMT flattop upper and wanted to rebuild but decided to grab a MRP and did not regret it. Best mono rail system IMHO. Solid, rugged, and made for hard use.

    Great mono upper for shorter gas lengths. This works with LMT piston barrels as well.
