GBBR LFS 4 Disc

[passey]

Has anyone heard or tried of these instead of an npas for GBBR's?

The look easier to fit and change on the fly if needed?

Cheaper as well £9 for a 10%, 15% & 20% reduction rings.

I've changed my NPAS for a 20% reduction one and its brilliant..a steady 315fps now on my we scar which is ideal for every site I use.....no messing about with a NPAS any more

Re: GBBR LFS 4 Disc

I bought a set for my WE M4, definitely better than an NPAS if you just want a steady, consistent, site legal FPS.

Be aware though that with some of the higher FPS guns like the M4/L85, especially with long barrels, the most restrictive disc will only just clear 340FPS, some sites might be a bit funny about that. That's the one I have in my M4 with it's 14.5" barrel but if I were to cut it down it would probably bring it down more.

If you have a full length M16 you may struggle.

I fitted the 15% disc in my OB M4 and it was reading 396FPS, so fitted the 20% disc not expecting that much of a change and it reads 360, 355 then consistent 330FPS.

I have been using the white '20%' disc for several months now in a OB WE M4 and get readings between 335-350 Max on propane in UK conditions.

Good bit of kit, much more consistent than the NPAS in my experience.
