Very cool. Dont think I've seen one in x39 yet. Did you use MRA pencil profile barrel?

The barrel isn't quite pencil...more of an intermediate built by MRA according to TNA's specs. It feels very well balanced.

Wait... We can use xcr-m mags in the modern Sporter lower?
Or do you mean xcr pistol mags?(I apologize in advance if I missed a previous post explaining this)
XCR-L Pistol mags ar-15 mags
Hahaha oops yes I meant xcr pistol mags!

So I made it out for a brief range session and it went better than expected. Got about 40 uneventful rounds down range (more on why only 40 later). It was a mix of Romanian and Chinese non-corrosive surplus. It all fed, fired, and extracted beautifully. Although I was shooting offhand accuracy was good. The rifle started to short stroke after about 40 rounds. I expected this to happen. I was using a Geissele Super Gas block on an undimpled nitrided barrel. I normally Rocksett my gas blocks but in this case I hadn't yet until I was sure it was positioned correctly for proper function. Sure enough it had shifted enough to cause the malfunction. I am absolutely confident that once it is properly mounted there will be no further issues. I have a bit of experience with AR platform 7.62x39 rifles and the 4 thing I have found to lead to reilaible function are 1)Full power or extra hammer springs 2)Enhanced firing pin 3)Quality bolt and 4)Carbine buffer. Needless to say I am extremly happy with the product ATRS have put out and look forward to shooting it alot more.
P.S. Magazines used were ASC XCR-L 10-round pistol. They dropped freely, fed beautifully and locked the bolt back when empty.
