Guess what, they only weigh 1lb 12.2 oz which is not at all bad considering you are replacing your buttstock, buffer tube, buffer, complete bolt carrier group (BCG), and buffer spring with the PDW Kit.
What we like even more is that with out getting one on a gun yet, we literally just opened the box, it appears that in the shortest collapsed position it’s only going to be about 4" long. Making the overall length of an SBR even shorter or a rifle nice and compact for CQB/Home defense along with storage and transportation.
Sorry for the amateur picture, and it’s a little hard to see with the dark back ground but from the point of the stock that will fit against the endplate of the lower receiver to the back of the shoulder pad is almost exactly 4".
When fully retracted to the furthest position back that distance goes to 8 and 7/8 inches with 4 other positions in between to help get the perfect configuration for you comfort and platform type.
