I've got a Seekins Billet Ambi lower on my SBR build. The lower comes with bolt release/hold. Right around $250'ish.

But: Then he'd still have to buy all the other parts and lego them together.

I shoot left-handed and share the same opinion of the above posts from other left-handed shooters. The upgrades I nearly always do to my AR15s are ambi selector and charging handle. The AR15 platform is extremely lefty friendly if your left trigger finger can reach the bolt catch/release.

Check out Palmetto State Armory lowers. They’re solid, usually under $150, so you’ll have some cash left for other parts. Plus, they’ve got a good rep, and building it yourself is half the fun

As a lefty, I'll echo what others have stated and endorse having an ambi-selector and charging handle. Having said that, I recently took the plunge and put together a rifle with the LMT MARS-L lower. Could I live without the ambi bolt catch/release? Yes I can, however, it is really nice having it. I shot stock, right-handled, M16's in the infantry and so forth; today I can afford to the luxury of something designed for me. Interestingly, the trend today is to field ambi rifles in the military, so there's that.

Lastly, IMHO, DO NOT buy a proprietary left-hand upper AR. It has a proprietary bolt and that can be problematic WRT parts availability. Again, just my opinion.

an ambi AR that might be a bit less pricey?

LWRC DI complete CHF rifle, fully ambi, at PSA, for $1709 + Tax

POF-USA Renegade+ DI rifle, fully ambi, at Central Florida Gun & Tactical, for $1889 no Tax

I own an LWRC AMBI DI and love it. I paid about $1500 4 years ago if I remember correctly. SmallArmsSolutions did a video on them not long ago but I can’t find it right now. He talked about the BCG quite a bit too. Awesome gun in my opinion.

^^^ That LWRC was on sale at PSA for $1300 a few days before my post. Such a good deal, I almost pulled the trigger on it, but decided against it because my wallet is no longer full.

The wife picked out a CAL LWRC IC the other day. Don't ask the price I couldn't get through to her, she hates money. But as every other experience I've had with them, it's a cut above. Seriously underrated quality wise I think. Came with an H2 and I like the trigger too.

I especially like how it doubles as a canoe paddle with the fin grip in case the bay floods, and the LOP is perfect for whoever the adjustable stock is "pinned" for. AND, it comes without a muzzle device so I can install my suppressor mount (brake) on it for when we go on vacation. (Middle finger to all commies.)

They had this Fully Ambi lower before most anyone else. I wouldn't hesitate to get their Ambi lower if I had to have one.

I’d start with a factory built lower for about $550 you can get the Daniel Defense complete lower with ambi safety and oem stock and grip etc and then get an upper of your choice. 13.9, 14.5, 16 etc. even if it’s a different brand. For 800 can get LMT lower. Add ambi charging handle and get to the range.

Don't forget a Magpul Ambi Sling Attachment Point and a good sling.
