BRT OPTIMUM Barrels

[Clint]

Yes, of course.

Should be a good combo.

YHM Turbo. The Backpressure king. We've corresponded via email. I'm patiently waiting!!! Super stoked.

As in "the YHM Turbo has high backpressure?"

@Clint

Has your team tested results or considered longer barrels, maybe an odd length as referenced in the post below?

This thread had me wondering about 18.5”, for instance, as a possible maximum point before drastically diminishing returns. Would the rifle length gas system be about optimum?

EDIT: Part of my thought process involved effectiveness (via velocity) of the broadest range of ammunition.

We haven't done any designs over 16".

The semi-popular 18" SPR is commonly available in MID or RIFLE gas.

We wouldn't do either of those systems.

The WOA and INT systems are much better choices for 18" barrels.

Just a heads up;
OPTIMUM SPR and PSD barrels are on sale.

^That's excellent.

I need to take a picture of it, but the rifle I built with the MPR barrel averaged a hair under .77"/100 yards for five 5-shot groups with 77 SMKs over H322. Groups fired from bipod with a rear bag. I look forward to building around your SPR barrel.

The wife shot her rifle equipped with the 11.5" suppressor gas drive barrel at a carbine class this weekend. Super accurate and super flat shooting. I shot some steel with it at our lunch break and was getting .5 second splits at 40-45 yards with little trouble. The only complaint was the rifle was a tad too heavy.

That's good to hear.

Regarding the weight;

There's over 18oz hanging off the end of barrel.

Any suppressor over 16oz is going to feel heavy.

A combination around 12oz will feel good.

This is possible with a direct thread adapter and no anchor brake.

These are combined weights including the muzzle device/mount.

The only complaint was the rifle was a tad too heavy.

The only problem is that that suppressor goes on about 5 hosts. It would be nice to dedicate a suppressor to that rifle. We ordered a Chimera from Silencerco. Maybe I'll direct thread that one to it. I may need to build a new upper with one of these barrels for my "night fighter" rifle. Between my 14" and this 11.5, I don't want to shoot any of my other dozen or so rifles!
