The impact/Dominator comes with 9mm & .209 adapters according to description:
Dynatex 'Dominator' impact BFG
Dominator impact grenade comes with string trip line and adapter for both 9mm and .209 primer blanks. Please check with your site before regarding rules for trip wires
The Timed BFG - the description says "
is available .... ", which by my logic implies it isn't included
(When I bought my timed BFG it was 9mm only and only adapters were the wrong ye olde type that didn't fit)
according to Timed BFG is says:
Dynatex's original Blank Firing Grenade is back!
The grenade you know and love is back in the game at a very affordable price. With a built in 5 second fuse, it is slightly longer than others on the market. Gives you the ability to cook it (not that we recommend it), and adds that tactical advantage.
Chambered for 9mm, a .209 shotgun primer adapter is available. Weighing in at around 250 grams, it is also lighter than other grenades on the market.
Supplied with loading tool.
But if they now include both adapters like the Dominator then fair enough
But timed BFG description implies or at least is a little vague it seems
No biggy, a sleeve is easy to knock up
As for loads of ammo, think
@sp00n won an auction bid and ended up with 1,000 for something daft like £35
(which I think is about the bulk price for Cheddite primers)
Think I got about 190 Cheddites (can't remember where from), & 280 Fiocchi's from JD Airsoft
(plus some 9mm blanks somewhere, be careful to buy good ones with hammer detonator
there are some blank pistol or starter blanks without the usual pin detonator and they don't work in BFG's)
