This is the upper attached to a Fulton Armory lower. It is a Douglas barrel from CLE 1/8. Upper is LMT ( I groung feed ramps into the barrel extension it was very east I copied the pictures from the feeding ramp post) handguard is Badger and Jewel trigger in this lower. I took my buffer apart and filled it with lead shot, I think it is now similar in weight to my 9mm buffer I bought. Next add is the grip from SPR.
My other lower(my first lower build) is waiting for a trigger part I lost during install, the trigger is an RRA 2 stage tuned by CLE and it is adjustable. I may have to buy a matching lower from (Laurel weapons?)
Here is a photo of my groups during load developement and break in. The squares are 1". the target with one large hole is 3 shots. Best load is 39 clicks (harrells measure) of AA2230c (surplus powder $60 for 8lb) CCI 41 mil primer and 50gr V-Max at mag length (chamber is short throat for mag length set up) 100yds 4.5X14 scope
Upper left and upper right is same load all others are .2 gr differant.
