PSA AR-9 Hybrid, Part 2: SBR’ed

 

If you saw the previous review/build post here, you’d know there was something we’ve been waiting on.

Well, after only 239 days, our Form 1 (e-filed, trust) was approved.  So, $200, 7 Months, and 25 Days, we’ve got our official Federal Government A-OK to put a different shaped piece of aluminum and rubber on the back of our pistol.

Transition was easy necessities were out of the way – that is, engraving the trust name on the receiver, making that a new SBR was manufactured, where and by whom, to match the approved Form 1, and what is now on the NFA registry.

On that note, I have to give a shout out to John Kleiber of Class 3 Weapons in Houston, TX.  If you need some engraving done, or want to skip the process and just buy an SBR’ed lower or full SBR (or just about any other NFA item you can think up), give them a call.

Once that was out of the way, all that was left to do was swap the Pistol Buffer and End Plate for a standard AR Buffer, End Plate, and Castle Nut.  Went with a low cost DPMS buffer tube, as I’ve used these a few times before, matching castle nut, and a PSA End Plate with a QD point.

And, finally, the transcendent moment where you put a stock on there.

I initially went with what I had laying around because I hadn’t decided on anything special yet, so it got an old Windham marked standard AR stock.

After shooting with it once, and deciding I wanted something a bit more stable, and running across one in my local Academy Sports, I picked up the flavor-of-the-month MFT Minimalist I’ve been seeing on 9 out of 10 posts on r/nfa lately.

The hype is well deserved though, its stable, with a nice wide contact surface, and gave a perfect fit on my buffer tube with absolutely zero rattle, while also not being too tight to move freely when engaged.  I’ve heard some cases where people have issues with the Minimalist being a bit too night, but the fit with the DPMS tubed seemed perfect.

It’s noteworthy that PSA has come out with a different model of this lower that has slightly different lines that make it look a tad more like the AR from which it was derived, and has the Last Round Bolt Hold Open feature.  While I like the design a bit better aesthetically, and LRBHO is a great feature – this is primarily a range toy, and that would be one more moving part to fail.
