Thread 'US Reaper Evaluation'

I will post more about the reason for the different events as time permits. For now, the information that I have.



308 win, 20” barrel, M118LR:

Reaper averaged 130.1 dBA SE



Control TBAC UL7 Gen 2 averaged 129.3 dBA SE





6.5 CM, 20” barrel, Hornady 140gr:

Reaper averaged 129.5 dBA SE



Control TBAC UL7 Gen 2 averaged 130.5 dBA SE




7 PRC, 20” barrel, Hornady 160gr CX:

Reaper averaged 133.7 dBA SE



Control TBAC UL7 Gen 2 averaged...

The OTB gained a 4db on average reduction. Very interesting when compared to the Raptor 8. I need to verify if the OTB comes with the can or is it after the fact.

Form hasn’t tested a Raptor 8 with reflex.

I am aware. I’ve read the other evals. I am working to determine my next can. I have standardized on TBAC and am disappointed they publicly are unwilling to consider OTB and replaceable end caps. I know my next can will be an OTB reflex and am weighing options. As noise Reduction is my primary requirement for 90% of my shooting.

Yeah, I understand that. After doing some more comparisons, particularly for unweighted sound values, I’ve been more impressed with TBAC’s overall performance. What amuses me, however, is how many people complain about certain cans that appear to test well. Cans that test relatively well in A-weighting don’t always do well on Z-weighting. The differences between cans’ A- and Z-weighting appear to be non-linear. But cans with better A-weightings sound better to us.

Based on comparisons of sound reduction (A-weighting) to length/weight, the Reaper looks very good with the OTB option.

What's the weight of the reaper with the otb?

If/when the OTB blast diverter accessory comes out it would be cool to try with some various cans...

OTB is likely a Jan 1 product, we still have quite a bit of development to do with it. I just weighed a reaper with an OTB, 12.2oz.

 

[Unknown Suppressors]

This is likely to change though as we finish the desing.

Thank you for the update.

Now I’ll go on an insanely silly rant about tone, weights, the size of Walt’s A$$hole and phrenology

I’ll buy you lunch if you know what movie that is from.

Enjoy the day. This is good news and thank you for the effort. Many of us are quite happy you’re willing to put in the time and resources.

Men At Work. Great flick.

Will it be compatible with any version of the tbac offerings? Perhaps a gen 2 ultra 5?

The DbA sounding better is probably because it has less high frequency content. Since A basically ignores below 1k, if a can is better on A and worse on Z it has a lot of low frequency content. If the spread between the A and Z is smaller, then the low frequency content is less. So if comparing two cans and Z is similar and A is better, then that can has less high frequency content.

If DbA is similar, but one can rates higher on DbZ, it has more low frequency energy that isn’t being included for the DbA results. Meaning it’s a louder can.

Could be why “tone” is a thing people talk about. I know I have recruitment due to nihl and it makes loud settings and high frequency sound unpleasant. My ears act like a high gain amplifier.
