2025年1月6日 · Hello again all, its been a while since I was last on but from my searching, it doesn’t seem like much has been discussed on use of MCX’s and FRT’s (Forced Reset Triggers). I was looking to see if a 3-position variant is compatible and someone on YT showed one working on a Rattler. But I...

2024年12月26日 · Hello, I am new to this forum and wants to see what everyone think. I currently own MCX spear Lt. it was 16 inch but chopped it to 13.7 and p&w. I am planning to swap my upper to 11.5. Obviously, I’ll be filling out form 1 it to sbr. But I am going constantly back and forth between sticking...

2018年12月31日 · Couple years ago with my 1st MCX, I called SIG customer service with basically the same question. I pointed out their confusing MCX manual's gas valve instructions. The CS guy agreed, saying the manual tech writers frequently wrote these instructions either before the weapon was actually produced, or with limited to no actual handling of the gun.

2016年10月25日 · Hi All, I am new to the SIG MCX and to AR15-type guns in general. I want to acquire some magazines beyond what came with my 5.56 MCX. Are any AR15-type magazines generally compatible with MCX guns, or must I stick to the SIG brand of magazines? If I can use other brands, what is a good...

2021年9月15日 · I was trying to see how a full auto function works on the MCX, it is plug and play with standard AR 15 lowers with an adapter, but I just want to know how they designed the military ones to work, or if the used a shortcut similar to the SU-15 or PMM sear bar and used a sear similar to the M16, used a sear on the front of the hammer like an AK, or how much is …

2017年3月26日 · Yeah, SIG ships different slings with their rifles, but mine came with a 3-point sling. Most guys train with a 2-point or single point slings, but these 3-points can work fine too. I use a Magpul sling that can quickly convert from single to 2 point setup that's very handy depending on whether you're moving around a lot, or standing in a ...

2016年11月24日 · The Sig MCX is shooting sub MOA groups utilizing .223 but I cannot shoot better than a 4.75 MOA group with XM193 and the best I could do with XM855 was a 1 MOA group. Results using XM855 were inconsistent but the Sig MCX consistantly shoots a 4-5 MOA group at 50 meters with XM193.

2015年12月16日 · So, broke MCX down, setup the breech bar and cheater drive in the vise, mounted MCX upper on the vise, locked a medium pipe wrench on SIG's MD - a firm pull broker her loose .. Ahhhh! Yeah, there's gotta be a 'but' - but, am not comfortable with how the Surefire MD's joins with the weird barrel cut on this MCX.
