Hi Royce and welcome. Yes, a 15" Midwest Industries handguard on a 16" M&P Sport II barrel combined with a direct-thread or HUB-mounted TiTrex 300Ti will produce a very tight, flush "tucked" look with minimal gap. The 15" rail leaves roughly 1" of barrel, which is less than the typical 1.55" threaded portion of the TiTrex, allowing the can to sit almost directly against the handguard. Cheers, stay safe and enjoy!

it should give you the look you want

Yes, great set-up and ultimate look.

Yes you will achieve the look you want with the set up you have.

Good evening to you!! Noveske makes a 15.5" handguard that will give you the look also. But if you have the Midwest Industries handguard, us a plan B muzzle device and plan B adapter to get rid of the gap. Hope this helps. Have a good rest of your day.

Yes, combining a 16-inch barrel with a 15-inch Midwest Industries Handguard and a TiTrex 300Ti suppressor will achieve a very clean, "flush" look with a minimal gap, provided you use the correct mounting method.
Here is the breakdown of how to achieve this, based on your equipment:
1. The Fit: Handguard and Barrel
16" Barrel + 15" Handguard: This combination is standard for creating a flush-look, leaving just enough room for the muzzle threads to be exposed, as a 15-inch handguard typically leaves about 0.8 to 1 inch of barrel exposed before the threads.
Midwest Industries Handguard Choice: To ensure the suppressor fits perfectly, ensure you are using the MI Suppressor Series Handguard (SP Series), which features a larger 1.67” inside diameter designed specifically to allow suppressors to "tuck" slightly.
The Gap: If you use a standard direct-thread mount, the TiTrex will butt up very close to the handguard end, usually leaving a negligible gap of less than 1/8 inch depending on the specific shims used.
2. TiTrex 300Ti Integration
Mounting: The TiTrex 300Ti is HUB compatible (1.375x24). To achieve the absolute closest fit, use a direct-thread mount, which allows the suppressor to thread directly onto the barrel and butt up against the handguard cap.
Diameter: The TiTrex has an outer diameter of 1.65". This will fit inside the 1.67" ID of the Midwest Industries SP Series handguard with extremely tight tolerances.
