I think you're right.  I'm drawing up a roller delayed upper.  There's a guy on Weapons Guild who built a receiver plate that essentially turned an MP5 upper into an AR upper, (to use on his registered machine gun) and that was pretty sweet too.


Bolt bounce is a little bit of a worry for me on the 300 blackout. This afternoon I was screwing around with the buffer weights and these are the two I'm going to use.

The first is a standard carbine weight buffer 3.1 ounces. The photo shows the total weight with the bcg. Very light!
http://i1035.photobucket.com/albums/a437/mark356/Mobile%20Uploads/IMG_20151227_143351_zpshjkrpadd.jpg

The second is an H1 weight. I used one of the FA buffer steel weights which is lighter than any of my other steel weights.I placed a tungsten weight at the rear of the buffer and the FA steel weight at the front.
http://i1035.photobucket.com/albums/a437/mark356/Mobile%20Uploads/IMG_20151227_143417_zpst0ulsfkb.jpg

My hope is that the tungsten weigh being at the rear will stop any bolt bounce but still tune the rifle to fire very fast like your setup. What do you think?


Yes it is


so that allows you to run the LWRC compact stock or similar w/ a normal bolt shaped/sized carrier???  This is very interesting...

did not know the mpx took ar FCG.   The mpx is the pistol cal gun right??  This is very interesting as this might be s better solution than a blow back AR.   I would love a bianary 9mm, but I hate blocback 9mm ARs.

Talked to the lead armorer at FA a few days ago. He was prompt, informative, and helpful. He was completely forthcoming to answer any and all questions I put forth. Not cryptic at all, which I like, especially when a company is marketing you some high-dollar item that's purported to do this or that...

Some of the questions I asked pertained to:
o ST safeties (no-go) - too much unique geometry to each side of the safety selector.
o Various lever offerings (no-go, for now)- he implied other companies may partner up to make a compatible lever, but they have no plans or ambitions to offer various levers at this time (seems like a mistake)
o Shims - they go in a pocket on the bottom, created for that purpose alone.
o Cut springs - absolutely no modification to their rifles, he said they're just using stock everything, period. Not fine-tuned or trick-shotted to get good performance. Acknowleged average person's capability to outrun carrier with standardized bcg's
o Shipping - he stated that shipping will begin mid-Jan on stand-alone trigger units. There is a good backlog building up though
o No modifications of any kind to trigger planned at present (although I was intrigued to see [in this forum] they were going to look into that plunger that puts resistance on the smooth pull) - when I asked him how far we were from the first, second, third, etc redesigns. I hate beta testing stuff to then see it $150 cheaper and on Rev III within 6 months. All the while having to send my shit back in, etc.

o Forgot to ask him about a flat blade trigger

To Fo or not to Fo...

You can run any carrier you want with the MVB stock. The buffer just slides into the end of the carriers. Its a weird little thing but it works great with all my carriers. It uses normal weights so changing those around is easy

I was able to test the trigger weight today.
In semi auto mode it was 6.0 lbs
In binary mode it was 5.0 lbs on the first pull. I could not get a measurement for the release pull because his gauge would not go negative.

At the range today I took a video of the two different buffers I wanted to test with the V Seven Ti BCG in order to see which one would work best for 300 blackout. I think the optimal weight range of BCG and buffer for 300 blackout is 10.7 oz  or maybe even 11 oz. I had two failures which had prime strikes with the H1 buffer. I did not have any problems with the carbine buffer but I did have the BUD engage once.  I ran out of ammo and I also had one guy come over and ask me if I was shooting full auto..lol

The 11.4 oz combined carrier and buffer had the two bad hits but the 10.7 oz had none. I think blackout is going to be tuned differently from a 556 in the BFS trigger. From my test I think optimal is 10.7 oz for blackout.

wow, even utilizes standard OD buffer weights?   Does it use normal action springs too?  effin brilliant.

This is making me rethink my plan to get a law tac folder.  Does that buffer work w/ any of the other PDW stock type receiver extensions?

Type III hard coat anodizing and a coating of micro slick.

 





The interior isn't cut as wide, so I'm hoping it will work with the BFS. If not I'll put it in a BumpSAW.

All weights will work in the buffer. I've switched out several playing with this trigger and other things not related to the BFS. The MVB arc stock does not use  a normal buffer spring. It uses a dual spring setup that is proprietary. I think they had to use the dual setup because they shortened the buffer tube. I'm not sure about the buffer working with other PDW stocks. I would think that MVB industries has it patented technology. The stock is a little short and I had to move the red dot forward on the rifle in order to get a good cheek weld on the buffer. However its a tiny little rifle that's good for HD imo.

Thanks, that is why I'm thinking it might be optimal for blackout. I would have to experiment more before I would know for sure. It was funny because right after I shot the second mag a guy appeared from one of the other range and asked if it was full auto. I thought i was in trouble but he had a suppressed sterling be was wanting to shoot. I got to see it rock n roll. Then an interesting conversation on the BFS trigger started.

yep.  Do the JP or the Aim if you want a steel low mass carrier.   That Aim surplus carreir is a helluva deal.  Don't sweat the F/A serrations.  F/A use in clearing stopages is dangerous.  Only good for chamber checks maybe.

Current plan is a standard carbine buffer, orange spring, aluminum carrier, AIM BAK-UP bolt on a 10.5" 1:6 twist barrel I have laying around.

 



I will also bring Tubb flatwire spring, Tubb 308 spring, Armalite 308 spring, DPMS 308 spring, standard carbine spring, AIM LW BCG, and an H buffer.

I sure would like to see high speed video with a standard carbine buffer and an aluminum carrier because see if that completely eliminates bolt bounce. Hell that even might be more  weights in as needed. I suspect with that aluminum carrier in an orange spring you are going to be running at around 1500 rounds per minute.

I would be curious to hear how it is that these things would do well with nine millimeter since nine millimeter stuff has to be so freaking heavy andit is not going to be able to be moving fast on both the ejection and chambering strokes. you might do one or the other but a nine millimeter blowback is going to run best moving relatively slowly in both the going into and coming out of battery.

also can someone explain why a nine millimeter does not use moving buffers? I guess the buffer stack could allow premature opening of the action depending on their position?

The interior isn't cut as wide, so I'm hoping it will work with the BFS. If not I'll put it in a BumpSAW.

Weight is 4.7oz with the gas key.

It's going to be interesting to see it run. Are you going to run it as light as possible? What's your plan?
Current plan is a standard carbine buffer, orange spring, aluminum carrier, AIM BAK-UP bolt on a 10.5" 1:6 twist barrel I have laying around.  

I will also bring Tubb flatwire spring, Tubb 308 spring, Armalite 308 spring, DPMS 308 spring, standard carbine spring, AIM LW BCG, and an H buffer.


1:6 twist? Whats that all about?

  Experimental twist rate barrel. There was a handful of us that tested various barrels for Green Mountain barrels here on ARFCOM.

Nice. I'll read the whole thread later. Thanks.

Yeah, I wish I had a high speed camera. It would really come in handy with aome of my projects.  I may throw an H3 and 9mm buffer in my bag to slow it down if needed.

 



As MUAD pointed out, the 1:6 barrels are from Green Mountain and were part of some testing we did for him.

also can someone explain why a nine millimeter does not use moving buffers? I guess the buffer stack could allow premature opening of the action depending on their position?

I'm planning on putting the next trigger in a 9 mm qc10 build. I know I'm going to have to file the housing in order to get it to fit. I hope i can be successful in a balance between the wt and performance without have problems. I have never taken my yhm 9mm buffer apart , now after you mentioned it I'm going to have to..

Yes please post a pic. I'm interested to see it. Mine is radiused too but it might be different. Since minecwill not fit in my QC 10 lowers without a mod.

I do not see any change from the one I got in my FA lower. Am I missing something? Thanks for posting the pics. I wonder why yours fits prefect but I can not get the current one I have to fit ,without a mod,  in either of my qc10 lowers.


Keep us updated on your tuning to get it to run faster.

Could it be that quarter circle changed there trigger cutout?

My number is in the high 1300

By the way there are shim pockets on the bottom and it comes with pull and peel shims

I have not used them yet because im playing musical chairs but when i leave it in a lower for good i will

I done about 100 rounds so far and what ive notice is you will have no problem with the secondary diconecter as long as you let completely off the trigger on the forward stroke

So the baest way to do this trigger in bionary seems to be by slapping it (shooting it like you have no clue what a reset is)

Could be. I purchased the two lowers when they first started and there serial numbers are in the first hundred. Once I get the other BFS trigger I'll know for sure.

New discovery. There is a slot machined beside the secondary disconecter (it what causes the disconecter to gao back) put some grease on a toothpick and put it in the slot it smooths things out alot

So much so that releasing it if it does get hung is not much more than a regular trigger pull weight

You jailbroke your trigger.

On my gauge the secondary is actually 1/2 bound lighter than the regular trigger pull now

I hate that i cant leave well enough alone

Btw im using the grease that came with my ss-e trigger

I measured 6 lbs on semi pull and 5 lbs on binary mode first pull. I oiled up the pack really well and it helped break it in better.
