The manufacturer doesn't state the weight of the UTG Pro AR15 Carbine Length Super Slim M-LOK Drop-in Rail. I recommend contacting the manufacturer for that information.
Yes, it is multiple parts that come together to build the handguard.
Yes, it should.
Yes, it will however it may be tight.
Yes, it should fit as long as your rifle has a carbine length drop-in handguard system.
Most likely not, the Springfield Saint models with drop-in handguards are mid-length, while this is for carbine length systems. If you do have a carbine length drop-in handguard, this should fit.
The UTG Pro AR15 Carbine Length Super Slim M-LOK Drop-in Rail will fit AR platform rifles that use a delta ring, front handguard cap, and carbine length gas system.
This UTG Pro AR15 Carbine Length Super Slim M-LOK Drop-in Rail is designed to replace carbine length handguards that use a delta ring and handguard cap. We do carry models that will extend past the front sight post in order to cover the barrel and allow for more rail space. You can find the UTG Pro model by using the link below:

Yes. This UTG Pro AR15 Carbine Length Super Slim M-LOK Drop-in Rail is compatible with your Colt AR15 as well as all AR15's with a Carbine-length DI System with Standard Delta Ring Assembly, Barrel Nut, and Round Front Handguard Cap.
No. Because of the barrel nut size difference between the AR-10 and AR-15, the handguards and rail systems are not interchangeable. I will link a category for handguards compatible with the AR10 platform below.
