Brilliant fun BB gun. Just don’t use Dust Devils. Bought some knock down IPSA targets from the US, best fun ever.


I Have tried to order this gun from my local gun shop, i was told it was unavailable and had been on back order since June

I first saw this at Ronnie Sunshines,at the time they were waiting stock, well worth the short wait. I fitted mine with a red dot sight (Get it from Ronnie’s) to make the most of the fast fire capability, Great fun to shoot and having a fast reloaded tool to fill the magazine is a bonus just keep it lubricated. Accurate, noisy,high capacity, great fun.

An excellent replica SBR. Looks like the real thing. Blowback action very realistic and provides a bit of recoil. Pretty accurate too at 10 metres. Speed loader works very well provided you use suitable BBS. I’ve used Umarex and Dust Devils, both load very smoothly. All in all, highly recommended. And dealing with Ronnie Sunshine’s is a pure joy. Thanks.


A lot of bang for the bucks. At under £300 this rifle is a lot of fun, an M4 type CO2 BB rifle, I'm quite surprised at how fast those BBs fly. It looks and feels authentic and although the automatic mode is disabled for the UK, you can still fire 25 BBs off in rapid succession. I've given it a 5 star rating because of the realism and fun it gives at this price point. I'm impressed.
