I'm going to replace the pinned stock with an adjustable stock and was wanting some feedback from those who have switched theirs outto see what seems to work best on these rifles? Will I need to purchase a new buffer ect or just the collasible stock and wrench to remove it with. Thanks for any help and advice.
You need the whole kit, as the pinned stock has a full length buffer tube/receiver extension. If you ask the trainers, the top three stocks are Magpul, Vltor, and LMT/Crane. I stuck my Sully fixed stock on my 6400.
I drilled out the roll pins and kept the plastic and tossed the post-ban tube. I'm going to send the lower in and have a Colt tube, plate and nut installed and have parts sent back with the lower to rebuilt the plastic.
