Great Quality, Great Price, A Perfect Start to a Budget Build

Anderson lowers are among the most affordable you can find, and they’re a fantastic value.  Forged 7075 T6 Aluminum with a Type 3 Hardcoat Anodized finished has been the military specification for decades, and for good reason.  This lower receiver mimics the mil-spec style of the M4 carbine, dating back to its inception in the mid-90s.  It has a fully adjustable 6-position stock, standard A2 pistol grip and lower parts kit, and all the parts come pre-installed.  No building required, just pop the pins and install a complete upper receiver, and you’re ready for the range.  Time and money saved in the garage means you’ll have more to spend on ammo, optics, and more.

High Value, Complete Anderson Lower

This is definitely a “no frills” Anderson lower, but there’s a few little upgrades sprinkled in.  The trigger group is of the mil-spec variety, but it has a stainless finish for a clean, crisp trigger break at around 5.5 lbs.  The adjustable M4 stock also features a QD attachment point, perfect for accepting a modern 2-point sling.  With the money you’ll save on more expensive lower receiver components, not to mention the time spent building, you can focus on accessories that will give you an amazing shooting experience.

I really like the lower. I’m going to be doing a stronger buffer spring for the caliber of rifle I ordered the lower for. I haven’t had a chance to run some rounds through it yet but I think it will function just fine.

Anderson lower

Bought this for a .22lr upper. Looks very nice but I haven’t had a chance to shoot it yet cause I still need to find a scope for it. I’ll probably take a scope off one of my other rifles and take it to the range. Then do another review.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Simple, easy, great price

As the title suggests, this product was simple and easy to purchase and have shipped to my local FFL. The price was great compared to other vendors, and I received my order very soon after ordering.

This is the second Anderson lower I have bought, and the product is great. The trigger is crisp and better than I expected-I do plan to upgrade it-but for it to be this crisp upon arrival was unexpected.

I have no complaints, I had never used AT3 before this purchase, but I plan to use them after this experience.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
