I'm starting this thread for that purpose. Any questions you have about parts, tools, techniques, tacticoolness, etc, put it in here, and I'm sure we can get answers for you.
I'll start

I'm building a poor man's SDMR.
So far I have a RRA lower with RRA parts kit.
I'm thinking about using an A1 buttstock, and putting an adjustable comb/butt on it.
Basically, I want to take the kydex sleeve from this:
adjustable comb
and put it on this:
adjustable butt.
This should give me a very low profile adjustable stock.
Does anyone see any problems with this plan? I know there are other options, like the magpull or the mako ssr25, but I really want this rifle to look pretty stock.
For the upper, I'm going to use a BCM 20" upper. I may eventually replace it with a custom upper w/ heavy barrel and picatinny gasblock, but for now it'll be the BCM.
I plan to use this handguard setup:
DPMS DCM free float handguards,
Something like these, but preferably in metal,
and a good bipod. Any problems or suggestions about this?
Not sure what glass or other optics I'll be running. For now I'll throw my Bushnell Sportsman on it, but I want something better. Planned use of this rifle is for shots between 100-600m. Any suggestions?
