Hoot wrote:Did Trident ship it with a magazine and did that one work OK? In your picture thread, you show what appears to be composite mags. How did they do? Approximately how many round do you have through the rig? IE is it broken in? If not, running it wet can help until the surfaces are work polished. Do the ASC mags come with a single stack follower or a conventional 5.56 follower? That last question is more to the jamming issue than no BHO.
Divide and conquer. If you're somewhere where its not a big deal to let a shot go or like me 10 minutes from the local range, here's something to try WRT no BHO on the last shot. Chamber a round and remove the magazine. Assuming you shoot right handed, take your left thumb and apply pressure on the BHO latch where it sticks out of the lower. Maintaining firm pressure on the latch, let one go. Don't worry, I've done this to TS people's rigs. You're trying to create the BHO action normally provided by the presence of a magazine, but without it. What you're trying to accomplish is differentiating inadequate gas versus magazine drag on the BC not allowing it to go back far enough to catch the latch. Feel the latch out with a magazine in and out. You'll get a sense for what the thumb has to do. Repeat a few shots to disqualify a random event.
If it stay open, you know beyond a shadow of a doubt that the mags are the problem. If it won't latch, you have to consider the issue being as I mentioned, lack of ease of cycling but more likely, you're right on the edge of adequate gas flow. I'm assuming you already checked the gas block registration, looking for the soot ring to indicate that it is located so that it doesn't obstruct a portion of the gas port in the barrel. Suddenly, I'm getting a deja vu feeling, like I recently discussed this.
Get the issue of gas supply out of the way before proceeding to magazine tuning and report back.
I sometimes overlook the obvious questions like, Does the BHO work when the action and BC have been recently cleaned, only to get spotty once it gets dirty?

Ill do the best I can replying
* No it didn't ship from Trident with mag
* (obvious you guys know your stuff) the composite mags in the pics were for the photo shoot and never shot with the Gun. Just the ASC mags are used. No mods to the mags, YET..
* Maybe 3 full boxes so far run through the weapon. Definitely not worked polished yet
*** I did just learn that Horandy just came out with newer version of the 450 called "Black" and am buying a case of it to have on hand to fix these issues... gulp.. Not cheap but hey God Bless America!
* ASC mags are NOT traditional 5.56 and is Single Stack
* I will be trying out the Non Mag thumb technique in early January and report back. I have loaded a single round - and then placed the mag in after, altering to the other mag to see if it worked - and either without Mag or With Mag it still does not hold the carrier open.
* Have a meeting with my Tech friend who actually supported the build. We took measurements to ensure the port and openings were large enough to provide adequate gas and found it did need opening more. That was done. Then in talking through your questions with him a bit ago - he had a great question on the Soot Ring asking me if I had noticed it was displaced or worse - missing.
I sit unable to extract the BC (because I am at work) but the moment I can get to it and disassemble I will report out.
Again I am not the most savvy of gun guy with terms - but am responsible to know its my duty to know, learn and functionally be capable of knowing my weapon inside and out. And not having the proper time to really break things down need ultimately - PATIENCE on my part. There are seemingly easy fixes. Not all apply when you customize the crap out of it.
PS I am a lefty shooter and the reason for most all things to be ambi-Dex. If I could have gone lefty on the eject port too. Dont think BM makes it to Eject Left.. or didnt two years ago...
