Thanks for suggestion. I looked at Trex mount you’ve mentioned but it’s kinda putting the light further away from the gun and light that I have is not Surefire. If I’ll use a ligh, ideally I want it or it’s mount to have a quick release so I can attach it whenever I need to and be mounted as close to the barrel as possible for better weight balancing. Since there is no substitute for IWC mount, maybe I can tey creating one, say a newer version. But I need an IWC mount still to take some measurements.

Very valuable advice, thank you. SBR are not allowed in country where I live and 1301 wasn’t available. Beside, I bought M4 because I wanted M4.

Just a quick review. Main idea is to decrease the weight. Stock aluminum T Pro handguard is 323gr, new TST is only 92gr giving 231gr of weight reduction. It’s made of polymer with aluminum Mlok inserts screwed in. Handguard is installed tight, zero rattle or play. Just what I would expect from Toni System. Elevated top end covers the barrel almost to the top. There is a texture on the surface, so there is no way your hand will slide on this thing in any condition. It looks very sturdy. It’s questionable how usable would Mlok slots be in the place they are as my hand covers them all. I assume front one could be usable with a forward extender for flashlight installation. All in all I’m very happy with it and can’t wait to give it a go at the range.

Oh, I see now. Factory forend is all aluminum and pistons could very well be hitting it as tolerances are tight. Very nice, so I can remove it using new forend. Thanks!

I have just received Toni System forend designed for M4 which I was planning to install on my M4 T Pro ro reduce it’s weight. But I noticed that I can’t install it as there is a part of the forend that interferes with this spring in the pictures. I noticed there is no such spring on M4 but it is on my M4 T Pro. If I remove it the forend installs flawlessly. My question is what this spring is for and is it ok to remove it, thinking if it would affect shotgun operation in any way?

Apparently there is a difference. I have just received Toni System forend designed for M4 which I was planning to install on my M4 T Pro ro reduce it’s weight.

Thanks for comparison. Are hand guards totally interchangeable? Can you out new one on the old M4 and polymer M4 on a new one T Pro? Thanks

Thanks. And location is good? I assume it should be on the upper side of the stock on opposite side for correct usage? I don’t have much experience with shot guns.

Are you still happy with this setup?

Do you have model for M4 T Pro? The latest release pf M4. Thanks.

I checked few related threads on the forum but couldn’t find definitive answers. I have M4 Gen 2 (Pro) and am planing to use Vortex Sparc Solar. My understanding is that mounting it on it’s own lower 1/3 plate will give no cowotness of iron sights, and mount is not QD. So I was thinking about integral mounts from Scalarworks Sync/01 and Midwest industries BENELLI M4-AIMPOINT T2 MOUNT. My question is if both of these mounts provide the same hight for the sights? I’ll use Aimpoint Micro footprint as I assume this is what Vortex is using. If anyone had an experience with Sparc, it would also be nice to know how these mounts will translate to Sparc Solar as full cowotness or lower. My preference would be lower cowotness. Thanks.
