Can you recommend an inexpensive optic that will drop on this while accommodating a mbus rear back up?
Baker19 on Nov 2, 2018
BEST ANSWER: A great Red Dot that has gotten even more "budget friendly" is the Bushnell TRS-25. It was my first AR optic and is still running strong 3+ years later. You can Co-witness it with your front site and change the Co-witness with different height mounts.
What's the best clip to buy for this rifle?
Mike B on Feb 20, 2019
BEST ANSWER: Doesn't accept ammo on clips. You will need to load ammo into a magazine and insert the magazine into the magazine well.
Does this come with a magazine?
Aaron on May 30, 2018
BEST ANSWER: Yes, it comes with one aluminum 30-round magazine.
Can the barrel extension and front sight be removed to replace with a m-loc style hand-guard?
Audie H on May 11, 2018
BEST ANSWER: Removing the barrel extension does not make this a SBR- Nobody can sell a gun with a barrel extension that is not permanently affixed if removing that extension would make it an SBR. If he wanted to, he could put a threaded cap on the 1/2-28 and it should still be legit. Any rifle that, without substantial modification, can be made to have a barrel length less than 16 inches from breech to tip is a short barreled rifle. Meaning, this isn't a 14.5" M4 with a birdcage to make it legal. It's a 16" rifle and the overall length of the barrel will still be 16" no matter what you slap on the end unless you make the extension part of the barrel in a permanent fashion.

I've been extremely impressed by the quality and reliability of this rifle. For the price there is nothing better. I have put roughly 600 rounds down range without a single issue. Wish I could say that about my Ruger 556.

Great rifle
Great gun for the money haven’t had any problems out of mine, it’s also a good gun to buy if you need something at the moment but also want to build your own and replace some parts or the all the parts of the gun over time especially if your on a budget.
My rifle and M&P Shield I got at one of PSA sales.

Awesome gun!!
Great gun,great price, haven’t had any problems with mine.

Well worth the money!
I served 8 years in the Army, with 3 years and 4 months boots on ground in combat in Iraq. I was looking to add another AR to my collection, decided to take a bet on PSA’s Freedom M-4. Took it out the box, put 30 rounds through it, cleaned it and sighted it in with 20 more. Burned through 200 more rounds that day with no hang ups or mis feeds, performed flawlessly. More accurate than the standard Chrome lined bore. Awesome rifle, couldn’t be happier. I’ll be buying more, great job PSA!

Good starter AR
I have no regrets on this purchase. It has run flawlessly and is very very accurate, even just shooting with the irons. It is pretty basic but good for someone just starting out. It has a good look to it right out of the box but I did wind up putting Magpul furniture on it eventually. PSA sells the same rifle with these items as standard, and it may be worth the extra money depending upon sale prices and what you want from it. I also put a polished trigger and MBUS sight, as well as a cheap red dot, but functionally otherwise I've left it stock and it'll work great right out of the box. When you get bored with it you can upgrade parts and learn how everything works.
