2025年1月28日 · My first addition to my new MPX (other than a few magazines) is a brace. I am torn between the MPX PSB from SB Tactical and the Sig-branded folding brace. So far, my reading says the folder is lighter and more compact, but I guess the HK fan in me likes the collapsable style too. Everyone has...

2021年11月19日 · Just got a MPX pistol and need to get a brace for it. I really like collapsible braces like the SB Tactical PSB more than the folding but hear that they are not that comfortable to shoot with. Is this true, and if so, what are the more comfortable braces to shoot with.

2017年8月6日 · Long story short: It's less expensive and less risky to buy an MPX carbine that comes with factory support and warranty. If BAFTE were to bring charges, the legal defense costs would exceed the carbine's cost in a few of hours of defense time. Bill

2017年10月9日 · Proud owner of MPX PSB here... Love the firearm, but the big clunky folding brace not so much. I noticed a "K" model is out now with what looks like a sliding brace. Anyone out there familiar with this or have one ? I am particularly interested in the difference in length of pull,if any, between the folder and the slider when fully extended.

2021年5月21日 · Will the SB Tactical MPX PSB for the MPX & MCX work on an MCX Upper mated to an AR15 Lower? I remember seeing a comment somewhere about the factory collapsible brace not quite fitting such a setup, but I wonder if the SB Tactical one will work. SB Tactical MPX PSB Here is a picture I found with a full MCX Rattler and this Brace:

2017年8月30日 · MPX PSB to Carbine Question Sig sells various length barrels and hand guards for the MPX. If you have an MPX PSB 8 inch, the change barrels to the 16 inch version and change the hand guard making it a carbine, is that legal?

2016年2月25日 · I went to the range yesterday and was able to successfully put another 200 rounds through the MPX without any failure to battery and/or failure to eject. They were all 115gr Sig Sauer ball ammo. I then loaded up a mag of Federal HST's to give that another go. AGAIN FTF on about 50% of the rounds. Took it home to give it a good cleaning.

2016年2月19日 · I am a long time lurker. I recently acquired a Gen 2 MPX pistol with the PSB and a MCX pistol with 2 barrels (9" 5.56 and 300BO) with the PSB. I am waiting on Form 1s to come back for both pistols. I would like for this thread to avoid the debate about shouldering a …

2017年1月19日 · The Sig website a couple weeks ago (like 2) had the MPX Pistol (Gen2) with an MSRP of $1500, that has since jumped to $1852. The same goes for the MPX-PSB, etc, etc. My local Cabala's had the Gen 2 PSB listed on the shelf/website just a few weeks ago for $1650, now its $1899. Many online dealers had the MPX Pistol (Gen2) for around $1200, not now.

2023年4月15日 · While Gen 2 rifles/pistols are able to make abundant use of Gen 1's MPX mags. Hell, I've got 30 10 round Gen 1 mags converted to 22 round mags that have worked flawlessly. Some hold a few more than 22, but that is the lowest number the mags will take.
