Durable, lightweight and great workmanship.

Very good- I can overlook the trigger

This is a nice lower. The M4E1 look is sleek, and I love the straight-line billet aesthetics. The SBA3 brace looks good on anything- That thing is a visual masterpiece. I thought it looked a bit “toy-ish” in pictures, but in real life it’s clearly a quality product.

<br>The trigger is somewhat heavy and it’s only single-stage. Unless you really like heavy, single-stage triggers, or just don’t give a darn, you’ll probably want to trade it out.

<br>I’m using this as a base for a self defense / SHTF pistol and I couldn’t be much happier. I personally think that the M4E1 is as good as it gets when it comes to duty-ready, no-problem lowers.
