Last year we had the opportunity to look closely at the S&T Specter M4 submachine gun replica with a folding stock, apart of a private collection .

Despite the positive first reviews, the replica did not gain popularity and production ended relatively quickly. Today it is quite difficult to get as its available in very few stores. That is why we noticed the offer of OctagonAirsoft, which regularly surprises us. At the store, the version without a stock can now be bought for 58 USD (yes, fifty-eight dollars).

Octagon does not provide any parameters. The one we tested generated a muzzle velocity of 340 fps. In our opinion, due to the limited or even "no" availability of the magazines, the replica is not well suited for regular airsoft games. However, as an interesting and rare exhibit in a collection, its a very god option. Even more so because the regular price for which you can still buy this replica is 109/140 USD (version without and with a stock) at Evike or 130 GBP at bbguns4less. 

And by the way... In the latter store you can also buy an equally rare A&K replica modeled after the KRISS VECTOR:

Also in the tan version.

The price regardless of version is 330 GBP.
