I purchased the Tacstar AMRS butt stock as a lower priced alternative to the Magpul PRS.
I was very pleased with the quality of the construction and finish of this product.
It fit my A2 buffer tube perfectly and functions as you would expect it to. It is
comfortable on your shoulder with a good cheek weld. The only con I can find is that
the cover for the lower Picatinny rail is a little loose fitting. I like it well
enough that I plan to buy one for another rifle in the near future.
