Agreed. At the time I SBR’d, SB Tactical hadn’t released the collapsible brace. The only option was to put an adapter pistol buffer and brace on. Which I didn’t like at all. Also, at the time it was “illegal” to shoulder a braced pistol. Now that SB Tactical and others have came a long way. Almost to the point where I wouldn’t mess with all the hassle. Especially with the ATF revision of the shouldering element.

Tell me more about the trigger and a Raptor charging handle. Hmm. I have a Gen 2 that maybe getting a integral suppressed barrel.My Mpx project (Which has consumed most of my gun funds over the last couple years) is coming to completion.
I started with the Standard MPX Gen 1 pistol.
Applied for SBR - waited a year (July 2016) and got my stamp.
Purchased an Omega 9k suppressor - ( again July 2016) got my stamp.
Had the barrel cut and threaded at 4.5” inch added 3 Lug device
Attached Rugged Flush 3 lug mount to suppressor
Installed Safe Harbor KES stock (liked it a lot better than the OEM)
Installed a BFS binary trigger system - hell yeah!
Sawpped out the oem charging handle for the raptor.
Swapped out the OEM grip with a magpul K2.
Trying to decide between the Sig optic and my MRO. Like them both but like the mro better on my AR. Not sure how I’ll end up.
Found a great deal on an MPX-K hand guard. That’s where I need help deciding.
Pros for “k” rail:
Lighter
Shorter - fits in back pack without suppressor.
If I shoot unsupressed (rare) the barrel is not tucked in hand guard.
Keymod for easy attachment.
Less potential heat transfer from can to hand rail.
Pros for original:
Love the shrouded look.
More space on rail for hand / accessories.
My questions would be, what looks like it would work better? Am I right in thinking that if I heat up the can, it will heat up the handguard? With the BFS trigger the can gets pretty warm. I thought about getting a high heat jacket for the can if I keep it in the “k” configuration. Which do you prefer?
Timney released a trigger for the MPX. I installed mine a week ago and its very crisp.
Sweet! I knew they were working on one that could handle the abuse.
Raptor.
The main reason I changed out the charging handle to the raptor is because I have a Gen 1. The factory charging handle would sag a little and wear a “bald spot” on the back of the reciever. I believe they fixed that in the gen 2. I do like function of it as well because if I’m holding it by the hand guard with my left hand, I can easily grab it with the right from the side and work it.
BFS
This trigger System has both semi and binary mode.
Semi is as normal.
Binary fires a round when the trigger is pulled and when the trigger is released. It’s pretty slick. It can be a PITA to install but it’s a lot of fun now that it’s up and running.
Thanks! I’ll try to get a video next trip to the range.
Thanks
I vote longer handguard.
