Precision Armament EFAB first impressions

[BufordTJustice]

BTJ, thanks for the ongoing review.

I would really love to see an honest comparison, cost differences aside, of the Precision Armament EFAB and the current version of the Knight's MAMS.

The KAC is a beast. I would expect it to be better in virtually every area, if only incrementally. I hold their kit in high regard.

For now the KAC MAMS is the pinnacle of hybrid devices. It combines the attributes of both items better than any I have found. Everyone else is trying to catch up. It offers close to open break performance with lower flash and and blast in 5.56, 300 AAC Blackout, and 7.62 than the competition has. It's not cheap, part of what you're paying is R&D.

Exactly. KAC spends more time and energy on one product like the MAMS than most companies do on their entire product line. Not to mention that they have C.R. Knight's elephant brain behind them.

Looks nice

Oh, and I ran another 120 rounds through the EFAB last Friday. The perceived blast to the shooter is basically non existent. It felt like my buddy's A2 on his 6920. Even from the side it is exceedingly mild.

Despite having the utmost respect for everything KAC, the EFAB has a shot at delivering almost everything that the MAMS does as far as flash, blast, and muzzle rise reduction (except for the MAMS' rearward recoil reduction) for about 50% of the price. If that bears out, that's high praise in my mind.

I need a MAMS to shoot back to back with the EFAB.

The EFAB works so well, you just don't think about it. I totally forgot to post about it, as evidence of this.

I hope you can get a hold of a MAMS and get a side by side soon. I'm about to order an EFAB and would like to see...

Don't hold your breath. I would love to, but I don't have access to one.

Oh, at that price, I don't blame you. I just like to see comparisons between products of all types.

I recently received a mint condition KAC MAMS 5.56 muzzle device (on loan from a member) and will be testing it against the EFAB on my upper.

Be looking for a new thread with plenty of pictures (and some duplicates from this thread for comparison purposes) and also some video. I'm actually going to find somebody else to hold the camera this time.

I expect the MAMS to have more reduction of recoil and to have roughly equivalent muzzle rise control to the EFAB. What is in question is the MAMS' muzzle flash reduction and back pressure increase as compared to the EFAB.

As I stated earlier in this thread, the EFAB creates virtually no additional back pressure and is excellent at flash reduction in my Rainier Arms 18" gov profile barrel with rifle length gas.

Your wish is about to be granted.
