AR Builders Any bad lower/lower parts kits combos? Which do you love and hate?

[Hop]

I have an older Colt HBAR that has the off size (can't remember if it is larger or smaller) holes for the LPK pins. Nice rifle, highly accurate but kinda annoying to say the least that it isn't totally compatible with my other AR-15 parts.

Hey, I have one of those too. I used it when we were at Atterbury. It has large pins and a steel sear/safety block. With some work & a Dremel you can get the block out. Then you can use the RRA 2 stage NM large pin trigger kit.

I hear Geissele also make a large pin kit. I don't know if it fits around that sear/safety block.

I put a Spikes enhanced LPK in an Aero Precision lower the other day.

Everything fit just fine, plus Spikes included an extra detente spring and plunger.

I've built 2 Tactical Innovations receivers with PSA kits (magpul grip, trigger guard, 6pos stock) without issue. First one was mated with upper from JSE Surplus (custom .223) good fit. Second one Bushmater's .450Bushmaster, it's a tight fit. Both shoot good without any problems.
Just need to figure out what to do with the third one I've got laying in the safe.
