Historical What-If: The CAR-15 SD
🕑 Added 2024-01-14 12:00:01 +0000 UTCWhat is the MP5 was never adopted, and instead the vented barrel and telescoping silencer used by the SD model was instead developed for the AR-15? Broad River Tactical thought it would be fun to follow this line of thought, and builds an MP5SD style barrel and handguard system for the AR - and I think it's a very fun and very cool concept.
This example uses the CMMG rotary-delayed blowback action, and EndoMag 9mm magazines in regular 5.56mm Pmag bodies. That means the whole system works with a standard AR lower, instead of needing a dedicated pistol-magazine lower. The silencer is a clone of the H&K SD type made by HiTec Arms, and it is a fantastically quiet combination!
Disclosure: Broad River Tactical send me the upper for free, and I put it on an SBR lower I already had. I bought the silencer. I have no other relationship with BRT or HiTec Arms.

aside the sd foreend those sights make it look very hkish. do the mag 9mm inserts work as reliable as a true 9mm mag? ok, the thing is kind of nice.

Nice build. I'd build one with the barrel available with can

Yep.

Didn't the DEA have something similar, but Colt covered the suppressor with an A2 handguard?

It’s sadly amusing that the AR lower, not the upper with the actual short barrel, is the SBR.

Nice homage to the ‘A’ team there, Ian. Kicking off another fine & informative video. Long time subscriber, still look forward to every video!

What an exciting carbine. One of the best things is small scale craftspeople getting an interesting idea and taking it through to fruition. Thanks from the UK where we can only watch from the sidelines.
