I finished my lightweight SLR build. The SLR receiver set is ok. I found some of the tolerances fairly tight but not sure if it was just the parts I chose. I couldn't use my v7 safety button but one from a Geissele LPK fit fine. My v7 ambi safety just barely fit and its very tight and takes quite a bit of effort to turn. The hole for the bolt catch roll pin seemed fairly tight to me. I went with a JP captured buffer spring but noticed the buffer tube/stock I chose did not screw in far enough to retain a buffer pin had I used one.
The trigger pack is interesting. I think it's easier to align things and quite easy to push the pins thru, didn't even need a punch. You have to do the install backwards though with the hammer first then the trigger. It can take a couple tries to get the springs to sit right when pushing the trigger pack in.
These are the parts I chose:
SLR receiver
Brigand Handguard
Faxon 20 inch pencil 5.56 barrel
JP ultra low mass BCG
Sabertube buffer/stock
Odin works rifle gas tube
JP captured buffer spring
Superlative arms 6.25 adjustable gas block
Phase 5 v3 bolt catch
Raptor LT charging handle
Magpul K2 plus grip
Geissele g2s trigger
V7 titanium trigger/hammer pins
V7 titanium grip screw
V7 furion titanium brake
V7 dust cover and titanium rod
V7 titanium ambi safety
V7 titanium magazine release
Phase 5 winter trigger guard
Scalar works rmr mount
Type 2 1 moa rmr
The weight of my build with optic and mount is 5.5 pounds. Without optic and mount was 5.3lbs. Could probably shave off a little more weight going with a lighter weight bolt catch, trigger guard, grip, charging handle, and gas block. Would probably be about 2-3 oz off with those changes but wanted an adjustable gas block and I like those parts. I was hoping to get sub 5 pounds and I do think its doable but wasn't willing to sacrifice on a few things. Here are some pics and of pics of it compared to a modern varminter and wk-180c.
