I meant the UBR because I thought it attached like an A2 stock and the adjustment is made on the stock not by sliding on the buffer tube. However I am not familiar with the UBR I have never seen one in person but the PRS probably would be better.
Well, if that's the case (and I'm not convinced that it is), you've precluded the statements in the rest of that post.Tirod said:The issue 6 position stock is relatively cheap and will fit a lot of shooters - but frankly, it's a finesse point. There is no data to quantify a percent improvement in accuracy - it's all heresay.
"There are no data" is an a priori disproof of the assertion that "it makes no difference." Not having any data means, quite specifically, that we do not know whether there is a difference or not.Tirod said:That's not ignoring sniper/olympic practice -just that the average 2 MOA milspec shooter isn't going to suddenly tighten up just because the stock is one position shorter. Shooter skill is much more the controlling factor, and of that, sight picture and trigger squeeze are undoubtedly a major contribution.
Back to back, installing an adjustable stock won't immediately improve scores, and some adjustable stocks can actually be a detriment with poor cheek weld, sloppy fit, etc. They are given more credence to justify their purchase than they actually provide.
