Not to beat a dead horse but I don't get how the SD-3G will fit or work. According to Geissele, they say it won't work but all over the internet, it looks like people are making them work/fit. The JP-5 trigger area is narrower than a traditional AR15.
What am I missing? Is it as simple as just putting it in or is modification needed? I dont care about warranty or anything like that but also don't want to spend another 200 bucks for something that isn't going to fit.
