Good looking shroud, reduces rattle of the oem plastic shroud. - Anarchy Outdoors Bolt Shroud, Ruger Precision Rifle

I haven't done any accuracy tests of any kind to say what this product does for function, but what I have noticed besides it looking alot nicer and giving the rifle a hardier look, is that it removed the slop compared to the plastic shroud which I always felt annoying and a bit cheap. The bolt runs smooth with it and have had no issues working the bolt.
