OK,I have to ask.
Is there any reason I haven't seen anyone with a vertical grip on their CETME/G3/HK91s?
do they not work out so well on the CETME rifles?
I have an aluminum tactical forearm on my
PTR-91 ,and a Tango Down Vertical grip.
I can't post pics.I keep spending my 'new cam'
fund on guns and ammo.
Most who purchase the PTR-91 prefer the classic look of
the HK-91 with a wide forearm.
I just wanted an extremely reliable,somewhat compact .308,
with effective accuracy out to 400 yards.
I think adding a vertical grip really updates the design,and helps
you to better control the weight of the 91.
I'm much better at standing shots with the vertiical grip.
I also don't tire out as quickly ,and stay more accurate
for a longer time.
With a rifle this heavy ,I can't see adding a light on it .
A quick detach for a Harris bipod is a good idea though.
That keeps it light ,and allows the quick attachment of a bipod if it's needed.
Add on a paddle style mag release,and a good optic like an Eotech or aimpoint,
and you can really lay down accurate fire at high speed.
That would be a great accesory.
The combination of a wood forearm and .308 recoil is why you don't see many forward grips. Any mounted grip will eventually be pulled away from the wood forearm it is mounted to. Furthermore the attachment opportunities are limited (this applies to bipods like those from Harris as well) and their isn't much mounting space between the handguard and the barrel.
One could get a G3 rail guard from B&T but you still may find a FVG uncomfortable. And if you are talking about a CETME clone then you may be shocked to discover a B&T rail costs more than the rifle.
In addition a full size MBR is not as handy to use with a FVG as a carbine. The ONLY time I have seen a FVG on a full size .308 is on the HK21 and the handguard is very different to accomodate it. Also the use of a FVG on a 21 is a bit different than on a G3/CETME.
