Hi folks,

Decided to replace the Gen 1 handguard with a Lancer CF M-lok handguard. There's not a lot of information out there about gen1 vs Lancer CF so I want to share this weight comparison.

TL;DR:
Gen 1 8" : 7.5oz
Lancer CF: 2.85oz


Came in this box
398166


MPX before the HG replacement, note the WML mount will also be replaced
398170


Compared to the gen 1 stock HG. All the online photos of the 8" CF handguard didn't have the vents and I was worried it wouldn't come with it but glad it did.
398167


Weight of stock gen 1 8" HG (7.5oz)
398169


Weight of the CF HG (2.8oz) less than half the weight!
398168


Old SureFire mount with Picatinny adapter (1.5oz)
398171


New Magpul offset mount for 300 series light (0.6oz)
398173


Surefire M300V with SR07 switch (5.15oz)
398174


Assembled back and 5.55oz lighter! (will need to do some cable management) Note, I opted to not use BUIS.
398175



Overall thoughts: The Lancer CF Handguard is a great functional, aesthetics and weight savings upgrade. It actually fits tighter than the stock HG. Less picatinny adapters mean less weight added when adding accessories. The MPX is a lot easier to move around now, no longer so front heavy. The balance has now shifted to the rear (which I prefer). Time will tell how durable it is. I wasn't sure how durable it was to attach a mlok QD point to it so I skipped that and opted for mounting the Magpul RSA to the last remaining rail slot of the body. If anyone has experience or knowledge if the CF is robust enough to take the stress of a 2 point sling feel free to chime in.

Great information and pics! I really like the Lancer CF handguards on my MPX and what's interesting is your weight shown above is lighter overall than the official stats listed on Lancer's website. I also have a Midwest Industries 14" handguard to use with my 16" barrel and am waiting to try one of their 8" models once they are in-stock again.

The profile is slimmer, easier to grab with the support hand, and much much lighter. In my case, going from Gen 1 sig rail attachment to MLOK is a big jump. What I really like about it is it balances the PCC better. Bought it from Big Daddy.

Howdies. About to get my first MPX soon in about 2 weeks so I'm doing some accessories browsing etc. And I love the look of the Gen1 handgaurd alot. So.. can it fit on my Gen3 I'm getting? And do they sell that style with the sig style rail in carbon fiber with the same look? I have a photo of the one I'm getting. I'll post it. But noticed it don't show the "K" anywhere on the guns box or tags. I'm sure it's a K tho. Or is K different somehow than what I have picked?

That's a K. I believe you can use a Lancer 4.5 CF rail but no, I don't think they have a version that has the Gen 1 Sig slots, that would be too difficult to make in CF. Best of luck!
