My new favourite case, neatly packed and speedily shipped. I am over the moon.
I had my doubts, because the picture isnt that clear. However when it arrived I was pleasantly surprised. Not only is this warm, the material and quality is outstanding.
This is by far the BEST Camo suit we have ever bought. We will absolutely be referring Gunmansa to all our friends that need tactile gear.
5 STARS ALL THE WAY!!!!
good quality
Haven't had a chance to shoot it but damn it looks so beautiful and realistic this is a 10/10 product!
A great product and does what it is supposed to do
Perfect replacement for previous unit. Plug and play option. No hassles.
Very satisfied with this purchase. Pellets are consistent, clean, and group well at range. Hollow point hits hard and the 500 count tin gives good value for money. Gunmansa shipped fast and the tin arrived sealed with no damage. Would buy again. 5/5
