I would say perfect cosmetic details are not a priority for LMT. If you want a show quality piece, look elsewhere.
In my experience LMTs excel at a few things: reliability, one of the best platforms for mounting NV lasers and clip-on NV (no worry about the hand guard flexing when on a bipod/tripod and causing a shift in the point of impact), better than average accuracy (especially in the AR-15 platform), the ability to easily change the barrel/caliber, a unique enhanced bolt carrier/bolt that works well shooting suppressed, and most items can be bought pretty easily from the factory or online vendors.
The negatives of LMT: IMO overgassed (can be fixed with BRT 50:50 gas tube), slightly heavier barrel profile (perhaps this also contributes to better than average accuracy, even in their chrome lined barrels, they do offer lighter weight profiles for the large frame platform, D. Wilson also offers Proof carbon barrel conversions), limited off the shelf barrel offerings given the proprietary barrel extension, cosmetic marks/defects (in my experience have not caused any problems with function), and they do sell at a more premium price point.
