So, I have been searching for a stripped AR-15 with integral trigger guard. ONLY ONE found at local gun show was a Mag Tactical Gen 4. I noticed it looked a little different. What I didn't notice was it is not the usual 7075 aluminum.
It's something different. Advertised as 35% lighter.
Does anyone have experience or advise regarding the durability and quality of this lower?

I will be asking for 12.5" pistol build advice on this lower in another post. Thanks in advance

By the looks of the trigger and hammer pin holes, the way they are built up, I'd have to say it's lighter because some of the "meat" has been removed from the trigger area and possibly the mag well.

actually didn't notice the dimpled trigger hole until after I got home. but, yes, you are right.....thickness is reduced.

thank you for the positive input and suggestion. muchly appreciated
Sorry for the short reply. Still making friends with a new phone....
I have over 800 rounds through one of mine. It is a 16" ARP that goes with me on every trip to Texas to hunt hogs. I haven't had any issues with pins loosening or anything else.
Build it, shoot it....and keep us posted on your progress!

Good luck with your new lower… I guess the only way you'll know if it fits your needs is through trial. Hope it serves you well.

Here's a good write up on the lower. Magnesium seems to be the metal in question.

I hope you have good luck with it, however, I bet the shop you bought it from was glad to get rid of it.

Personally I’d see if they’d take it back

I used many Mag Tactical lowers in my ultralight AR builds. They work great, the magnesium is a blend with aluminum. So lighter and just slightly less strong than 7075. Heck I have half a dozen lowers using polymer lowers. The only issue is don't loose those longer trigger pins! One of my lowers came without the longer pins! Also some buffer tubes are really tight into the threaded area of the lower. I looked at the problem and used some gease, then eliminated the castle nut. I always thread the rear hole for the selector spring and use a 4/40 allen screw to eliminate the end plate.
