Mounted this on the front of Ruger PC Carbine 9mm rifle handguard that had no front sight post. A standard Picatinny rail to mount was too high to prohibiting the installation of a flip up iron sight since it was then higher than the receiver's rail. The lower profile of this piece enable the installation of Meprolite's Trid front flip up post. It's well made and worked perfectly.
Pros:
- Low profile
- Construction
- MATERAIL
Would recommend: Yes

Wish this was included with the rifle as this is needed to add front back up sights on the Sig M400 if you are also running an optic. Well made and easy Mlok installation.

The item was perfect. But for some reason they decided to use DHL to ship. It took forever! I don't understand why they would to that.

After searching numerous web sites with intent of purchasing the Sig Sauer spacer(picatinny)rail for the front iron sight of my new Sig M400 Tread I was happy to find it at a great price at Optics Planet.

Works great. Works exactly how it ought to. Like it should. Like sig would. Like they should. I love the sig m400. Nice Molly rail sight attachment. It’s the perfect height to line up your back sight to get accurate shots at the range.

I was on the lookout for a slightly lower profile rail section so I could add a rail on the top section of my Lancer Carbon Fiber handguard. It's been shockingly hard to find a rail that will mount at the same height as the receiver rail.
This one does. It may be made for the Sig TREAD, but it also seems to be the right height for other rail systems lacking a built in rail section. As long as you have an MLOK slot, it should give you the option for a sight rail.
Pros:
- EASY INSTALL
- Quality build
- low height
Best Used for:
- hunting
- Target shooting
- Tactical

Good for mounting a front back up iron sight on the Sig M400 Tread rifle or pistol because it matches the height of the upper receiver on the Sig M400 Tread it's a metal rail segment it's pretty durable only con is the price
Pros:
- Matches height of Sig M400 Tread upper receiver
Best Used for:
- Mounting a back up front iron sight
Would recommend: Yes

Obviously this sight rail is made by sig for the tread so it’s perfect for the tread. I have basic mbus sights as backups and this piece of rail is perfect for the front sight. The rail section is small and that’s obviously what’s intended it’s just long enough for a sight and it keeps the hand guard simple and clean.
