Hey hows everybody doing? I decided I wanted to get into shooting .308. Ive never had one before or built anything other than a few glocks. But I am an engineer, have designed and built houses, cars etc…. So I figured wtf how hard could it be to throw together a lr 308? I thought it went smooth, until I got everything together and tried to hand cycle a few rounds. First rack chambered a round perfectly, bcg went into battery, everything was fine. I pulled the charging handle, it ejected beatifully…. But then the next round chambered half way. The bolt wasnt fully closed and no mattery what I did, the round wouldnt seat properly or eject. I hand to take the upper off of the lower and pull the round out.
Heres the parts List:
-Aero M5e1 upper & lower with 15” enhanced handguard
-Aero LPK minus FCU & Bolt catch
-B.A.D. Extended lr 308 bolt catch
-Geissele SSA-E Lightning Bow
-Aero m5 nickel boron BCG
-Aero m5 enhanced carbine length buffer system
-Radian Raptor ar10 charging handle
-18” spikes/fn .308 chf cl barrel (although its stamped 7.62, spikes says both are guaranteed by fn)
-Superlative arms .750 adjustable gas block
-Spikes proprietary length gas tube
-Precision Armament EFAB (with pa crush washer)
-Magpul UBR gen 2 stock
-Midwest 30mm qd scope mount
-Trijicon accupoint tr26 2.5-12.5x green moa
-Arisaka 35deg offset mount
-Holosun 508t red dot
-Magpul MBUS front and rear flip ups
-DD enhanced vfg
-Magpul bi pod
-Lancer L7awm 10rd trans smoke mag
Everything was put together with proper tools, torqued to spec and lubed better than an elizabeth nj escort.
I would just appreciate a little input as to whether this is something I should be worried about (like take to a gunsmith to get a green light). I’ve read that lr 308 builds have a pretty extensive breaking in time. Ive now tried hand cycling it 4 times, and after the first round cycles perfectly, the second always does the same thing. Thanks for your guys help.
