Chapo Posted October 2, 2022 Share Posted October 2, 2022 Bought a PSA GEN4 8" 9MM 1/10 GX M-LOK MOE EPT SHOCKWAVE PISTOL without realizing the importance of having the bolt hold open feature. Trying to use the carbine for competition and it’s very cumbersome without this feature. My question is, is there a way to get that one part and install it or do I need an entire receiver. If I need a receiver how do I know which is compatible? Mine uses glock magazines Link to comment
ChuckS Posted October 2, 2022 Share Posted October 2, 2022 Please explain why you want that feature. I actualy disabled it(removed the wire) on my NFA uppers because all it ever did is get in the way when cleaning the gun. I never needed it in a match! I run 40 round (actually 42 but I can only reliably count rows in cartridge boxes these days ) mags and that covers all 32 round stages. I use pistol mags for classifiers and standards but always reload on a closed bolt. Link to comment
Dirty_J Posted October 2, 2022 Share Posted October 2, 2022 Unless you’re shooting IDPA exclusively, there’s zero reason to have this feature. Not only does my Davinci lower have any LRBHO features removed… I’ve even removed the bolt catch. Link to comment
Chapo Posted October 2, 2022 Author Share Posted October 2, 2022 I’m using it for shooting matches but sometimes I loose count of the spent rounds and loose time between figuring out there’s not a bad primer and changing mags. Link to comment
Chapo Posted October 2, 2022 Author Share Posted October 2, 2022 I guess I could buy more magazines that have more capacities Link to comment

Glock 31rd magazine with a + 10 extension is standard fare for shooting a Glock PCC. More than enough rounds to finish a stage at most type of competitions. No mag changes needed. Link to comment

PCC is all about big mags. With that in mind, don't count "spent rounds" and count make-up shots. Say a stage is 32 rounds and you have 40+1 at the start, you only have to count to 8 before you reload . And if you need that many makeup rounds, you may need to look at other issues Link to comment

Braxton1 Posted October 4, 2022 Share Posted October 4, 2022 The reason I won't run LRBHO: On PCC's, the bolt REALLY slams into the Bolt Catch when it lifts (especially on "stroked" guns, which is what I build). It gets a good running start on the Catch and when it snaps off, it is a guessing game as to which piece of aluminum it will imbed in. Link to comment

Chapo Posted October 6, 2022 Author Share Posted October 6, 2022 Thanks all. Seems the way to go is larger mags! Link to comment

IMHO, Even though you know you have to reload, it’s faster to reload & simply hit the bolt release than to run the charging handle. At least it is for me. Also, that’s the way I run my AR rifle, so operating the gun is the same for the AR style platform & not dependent on PCC vs Rifle. Link to comment

I have the same experience as this and was wondering if anyone knew of an upper that has a LRBHO that would play nice with the PSA lower. We also have these "warm up stages" where reload is required and not having LRBHO really kills my time. Even if I had a side-charging upper, bolt release is still much faster after slamming the magazine in. Any PSA owners here who can chime in? Thanks! Link to comment

Dont ever let the gun dry when you reload and you dont have to do either. If you want bolt hold though then you need to get a different receiver either upper or lower. The aero epc upper has LRBHO in it, if you insist on having it. Link to comment
Seanzky Posted February 20, 2023 Share Posted February 20, 2023 It's not about running it dry. The stage REQUIRES a reload with only 6 to start with, for example. I can't cheat, put 7 in there so that I don't have to chamber a round after reload. As much as possible, I don't want to change out the lower and have to buy another magwell. I posted on this thread hoping someone out there who has a PSA AR-9 and has changed out the upper to one with LRBHO can chime in. I did look at the Aero lower and upper pair. For ~$215, it's not bad. I just hate the thought of having to buy another magwell and then do all the work to change out the lower, too. Link to comment

Let me try again. If you want LRBHO then put the aero epc upper receiver on your PSA lower. I havent done it but I have seen others do it with success.

I just might go that route if others can corroborate the compatibility. As for the game I compete with a PCC in, it's IDPA. Certain scenarios call for a downgrade to your first mag as someone stated above. Link to comment
SnipTheDog Posted February 21, 2023 Share Posted February 21, 2023 (edited) Have an Aero upper and lower EPC. Toolcraft bolt. Aero PCC buffer with an AR10 spring. Last round does not hold the bolt open. I think I can trim a coil or two until it locks back. The PCC so far is just for fun and not for competition. Any other areas to look at? Otherwise, the gun runs surprisingly well with factory Fiocci 115g and my hand loaded 147 grain RN bullets. Edited February 21, 2023 by SnipTheDog Link to comment

The upper I run is Aero EPC9 w/ LRBHO. I also run TacCom ESSB bolt and Taccom adjustable short stroke buffer. The LRBHO works 99% IF I use Glock Gen 3 mags. Other mags are not consistent. I contacted Aero and they confirmed that Gen 3 mags are the best option. some people have suggested bending the part that actuates the LRBHO but I have not even started messing with that. I have an adequate amount of Gen 3 mags. Edited February 21, 2023 by mitommy Link to comment
