Got my pistol finished over the holidays. I ran about 150 rounds through it last night and it ran flawlessly. I haven't gotten my three lug adapter yet since my Obsidian suppressor still has time left in purgatory. Parts listed below
New Frontier Army C5 upper
Faxon 9mm bolt group w/removable weight
Faxon 8.5 inch straight barrel
SLR Solo 7.5 inch rail
DPMS milspec trigger group
Magpul flip sights (saving for HK sights)
