研究Blaser TAC 2讨论的时候，发现为什么FBI当年没考虑TAC 2，原因就是TAC 2上面的注塑枪托。

I had a few in my possession for about three years, in .308, .300, and .338. Long range rifle shooting is way out of my area of expertise, but I can tell you what little I know:
The bolt is ridiculously fast once you learn to use it properly.
The safety is goofy and takes a bit of getting used to.
Accuracy is outstanding ... We did a test at Yuma Proving Ground, a professional shooter put 5 shots into a 4" circle at 1,000m in a 5-15 mph variable crosswind. There were many witnesses, most of them from the military sniper community. It was pretty impressive. Gun was a stock LRS-2 .338.
There are a lot of bits and pieces that make snagging other pieces of kit, branches, etc. too easy. The gun would definitely benefit from a redesigned stock.
You can change barrels or calibers very easily. I believe the current configuration stock allows you to have either .223, .308, .300 or .308, .300, .338 depending on which variant you choose. The optic is attached directly to the barrel and, in my experience, provides adequate repeatability that I could never tell that the barrel had been off the gun, even after multiple iterations.
The muzzle brake is a farce on the .308, it's not needed and it just makes the gun bigger and louder. On the .338 it helps ... a number of folks I shot with agreed that the .338-with-brake felt almost identical to the .308-without-brake.
Because of the design, you can switch the gun from being right-handed to left-handed in, literally, five seconds. This assumes you pay the exorbitant price for a second bolt, of course.
A folding stock version was nearing the end of development as of the time I left SIG (Sep'07).
The monopod in the butt eliminated the need for sandbags or other fine tuning aids ... a little twist of the leg and the run would rise or fall until you were perfectly on target.
Magazine capacity wasn't particularly good compared to many competitors.
There was a recall about two years ago, some foreign soldier picked his off-safe rifle up from the trigger guard and discovered (to his extreme dissatisfaction) that you could trip the trigger without touching the shoe. So SIG got all the rifles back and added a little plate to the top of the trigger guard preventing that in the future.
The LRS-2 was disallowed in the FBI sniper rifle trials because it has an injection molded stock. Even though the rifle has survived many extremely grueling durability and stress tests, FBI rejected it because their spec said "no injection molded stocks."
