Yes. It's labeled the Freedom-15. I picked it up during last year's Memorial Day sale.

Looks good Andy

I took it to the range tonight to do a basic function test. Since this was my first time to build a gun, I was a little nervous.

The magazine caught fine and the first round loaded without any issues. First round fired fine but the second round loaded but didn’t reset the bolt I guess. I manually cycled it and it fired fine. Then I had another click and no bang. Again manually cycled it and it worked fine. After that, there were no issues.

I’m not sure why but once it got going it was fine. I ran a little over 100 rounds without any issues.

As mentioned, it’s loud and breathes fire. I didn’t worry about zeroing this time, so I’ll be going back to zero the sights now that the few hundred rounds fired without issue after the first issue.

The folding stock is fine. It’s a little stiff, so it didn’t want to latch and when it’s latched, it doesn’t want to release. But folded, it fits nicely in a backpack.

Are there light primer strikes? Check the hammer spring. I installed one backwards that resulted in light strikes.

There were no strikes at all. It looks like the bolt didn’t fall back into the battery. I think it didn’t have enough lube o. It and after I cycled the bolt a few times it was fine.

It’s possible but, you might of had a burr in the buffer tube that worked it’s way smooth after a couple of cycles. Either that or your buffer is too stiff. What brand buffer tube are you running?
Do you know if the inside of the tube is smooth or if it has machining marks? Those marks cause a lot of drag on the spring and buffer.

Remember, you have a short barrel so a lot of that gas is escaping out the front (hence muzzle flash). This plus the pistol length gas port don’t really push the bolt back with much force. You might have to get a lighter buffer spring.

Since you said you didn’t have any more malfunctions after those couple of ones, I’d say you will be fine and just shoot the crap out of it.

I didn’t take pictures, but I took it to the range this morning to zero the red dot sight at 25 yards this morning.

No malfunctions at all. Very smooth. Got it sighted in and ready to go. Nice little in-house AR pistol.

That’s great Andy!

I really like that folding stock setup. I just saw the part advertised in the last couple of weeks.

The cool thing is that it fits in a backpack.

Yes we love you. Now boy shouldn't you be off pedaling somewhere?

Very interesting contraption, I will be looking into it. Right now I think the can is a must. I've got a couple of books on the subject, going to do some reading on it. At least change the hider style to push the blast more forward.
I went with the primary weapons systems upper because it's a direct link piston setup similar to the AK design. Very clean, slick action, I like it more than my Ruger SR. Though the real find was the Velocity trigger, the straight blade no takeup thing is amazing. At 3lbs. It's the closest thing to a 1911 glass break style in an AR that I've seen and it's drop in! Sure hope it stays that way. It had a lot of rave reviews, not a bad price @ $150 but the little bugger is never in stock.
