all in one kit Review by mark
Installed the LPK into a M5 lower receiver and the parts fit very well. I am new to building AR's and the only two criticisms I have are that some sort of instructions would be nice to have i.e. how the trigger spring and hammer spring are supposed to fit together. Also, the pistol grip was very snug fitting on the receiver making it difficult to attach and keep the detent springs from binding up. Overall, kit went together well. Please keep in mind this review is from a noob...lol. (Posted on 6/28/2018)
Parts Were perfect when left warehouse - but SLOW Came late - poorly packed with bent spring and missing detent Review by BPA
Waited 2 weeks for kit - they sent it on the 7th business day wwhich they waithed for MLK day to ship so one more day

finally gets here and box is huge

packing state of the art
box for kit nice
then all the parts in one bag in the center like a washing maching



Love Aero But Had the last couple of orders drop the ball

DOnt know whos gonna pick it up and run

Who knows maybe an exec at Aero will see how much im ordering and send me a couple lpk's on the house

u never know

and please send major parts in separate bags

i mean the hammer and trigger at least separated please!!!!!!!

all the packing in the main box wont help but keep parts box so pretty

but the parts will look like chicago pavers

good w pavers but not with mil spec parts

so fancy packing wont help that issue

just some tiny small zip lock baggies or military cellophane (cheaper) i do military packing

or even foam wrap for the short term ship(Sorry not milspec lol but ill take it)


I may sound a little bitter

Well i am Especially when the customer service lady was rude

and usually they are very nice ?

Win some loose some

but this time its a good customer ! : (

Hopefully i can update this review for the better (Posted on 2/13/2018)
