$50 forged AR-15 lowers from SI Defense


Lower receivers CNC machined from certified 7075 aluminum forgings and anodized per Mil-A-8625. Lower receivers are marked with “multi-use” for use of different calibers.

I had never heard of SI Defense until now.  I’m sure after this deal they will be a lot more well known, especially if the lowers are quality.

$500 for a custom logo though? LOL that seems a touch excessive!

$10 extra for clear anodizing, or $40 for colors is definitely reasonable though.

Too bad I already have more lowers than uppers :(  I’m sure they will have enough orders to keep them busy, without one from me.

I would love to hear more about the quality on these. Looks like a nice thread is forming: http://www.ar15.com/forums/topic.html?b=3&f=4&t=473202&page=1

Hi Nick,
You’re right, the link appears to be dead. I found another link on their page, but it looks like they are out of stock on them:
