I'm looking to see if anyone knows where I can find a lower parts kit for a SCAR 17. I have a Timney trigger in my HANDL lower already, so I'm looking for a parts kit like HDD makes, preferably without the trigger parts. I tried to use MW's website to piece something together, but they seem to always be out of stock of certain parts. I'm basically looking to use my factory lower as a spare/back up just in case the need arises. Any recommendations?
