MP5-SD Shroud V4 (Optional Pic Rails & Tri-Lug Support)

Video of dumping 2 back to back mags of binary with V4
EDIT (6/5/2024): V3 and V4 release. I have personally been using V4 for 2 months no issue in pa6-cf. The default clearance is made for an omega 9k which is 37mm, but the diameter of the hole itself is 39mm. V3 and V4 Shrouds your suppressor a little bit for a more cleaner look to hide your mounting solution, with V4 having the option of: A single bottom pic rail, dual side pic rails, or a tri pic rail setup on the sides and bottom. The V4 and V3 attachment is a little tricky to attach while minimizing the strength of spring steel of the rubber handguard, I will include a tutorial to best attach shortly. 

If you would like a modification for a different diameter suppressor, feel free to ask and I'll upload it for you

EDIT: V2 has been uploaded with support for a tri-lug mounted suppressor. I have tested it so far with a Rugged and SilencerCo Tri-Lug. 300+ rounds no issue (PA6-CF)

DO NOT USE V1 IF YOU WANT TO SHOOT SUPRESSED WITH TRI LUG!!!

V1 of an HK MP5 SD Shroud for use with a purchased MP5-SD handguard online such as the ones found at: www.broadrivertactical.com. I designed this to allow others to refine it, make it better, and easy accessibility to those who don't want to spend their own 70+ dollars on a 3D printed part. I have put atleast 350 rounds through a PA6-CF print with no issue so far (as of 4/5/24)

not sure of fitments of other MP5 clones.

will not work on 22 LR clones/mp5

please remix this if you desire and share it for all as I have only my own personal SP5 to test fitment and my own handguard purchased from BRT

install:
slide shroud into mp5
slide rubber handguard over shroud from the barrel, do not attempt to attach it from beneath to avoid ruining the spring steel's elasticity
