Quick update. I’ve ditched the PSA idea. They missed the late summer estimate and moved it to 2020. I bumped the thread on ARF to see if they had an updated estimate...and they deleted the whole thread.
Ended up ordering a QC10 lower. One advantage of that route will be LRBHO, which I believe the PSA offering didn’t have. In addition to the pic a couple posts up, I have ordered
1. QC10 lower that takes .45 Glock mags
2. 10.5” upper from JSE, including CH & BCG cut for Glock mags (barrel and rail are both 10.5”)
3. 8.2oz buffer
4. PSA SBA3 EPT MOE LBK (enough acronyms?)
I also ordered a 12” rail, but I think I’m either going to return it or sell it. I didn’t think the rail on the JSE upper was going to have a large enough ID to tuck my Octane, so I ordered the 12” which was advertised as 1.81”. Then I found out the JSE has a 1.57”, which will look a lot better with the 1.375” silencer. I’m going to have the barrel cut down so that the Octane 45K sticks out just enough to grab it. If the rail will slide over the silencer, I may even cut it so it’s closer to flush...so I’ll install the rail after I’ve tightened down the can.
Rail came today. LBK is due here Monday. Got a shipping notice from JSE for upper and buffer today, but haven’t seen any movement. Haven’t heard anything from Quarter Circle on the lower.
I’ll get it all assembled and test fire it before I send the barrel off to get cut down. It’s threaded .578x28, but it’ll be 5/8-24 when it’s done.
