I've been lurking around this site for a bit and haven't exactly found what I'm looking for. I have a the latest LR-308 high profile upper and am wanting to replace with a low profile upper. I searched and couldn't find anything about AR-Stoner on here. https://www.midwayusa.com/product/597968/ar-stoner-upper-receiver-assembled-lr-308-a3-matte
Also, can I just use a Davidson Defense complete upper like this? https://davidsondefense.com/dpms-lr-308-upper-receiver-demon-assembled-upper-18-match-308-win-1-10-t-4150-cmv-barrel-17-je-machine-m-lok-handguard/
Thanks in advance.
