The Winchester MP4 Co2 air rifle has a tactical style and features that will make you fall in love with shooting all over again. The quad weaver/ picatinny rail gives you plenty of options to mount your favorite optics to your liking. Already equiped is a flip-up front and rear adjustable sight, so you'll be ready to aim and fire immediately. Exclusive to the MP4 is the textured pistol grip and adjustable buttstock that will leave you feeling dexterous as you shoot. Hidden away in the magazine are the two 12g Co2 cartridges that power the MP4 and the 16 round clip. The dual ammo rifle shoots .177 caliber pellets or BBs at an outstanding 700 feet per second.

Good rifle, bag magazine.
May 13, 2016
I have owned this rifle for about 2 years and have put maybe 1000 pellets through it and when it runs smoothly it is a dream to plink and have fun in the backyard. My only downfall was with the double-sided rotary magazine, it would jam certain pellets mainly my go to pellets i.e. CPHP, JSB exacts. I would fire H&N copper coated pellets for days and as soon as I filled it with regular lead pellets it would jam after the first side. I have seen another fellow who contacted daisy and got more of these magazines and has had no problems. I will soon be doing the same, the only reason I have had it for a couple years and not done so is because I stepped up to pcp's. Overall whether or not I got a lemon of a magazine, I would highly recommend for backyard fun, oh should I mention it is quite quiet.
"Tactial" feel, adjustable buttstock, realistic mag release, eh trigger.
Rotary magazine.

Sturdy and reliable

Great gun
Dual ammo, durable, strong enough to hunt small game
The gun can jam when using bb's if the bb becomes dislodged from the rotary clip. But it can be fixed with a hard trigger pull

Excellent gun!

This gun is amazing. I got it for Christmas and I love it so far. It has a high rate of fire and has a bit of weight on it. The pictures are the gun with attachments on it, scope is on its way.
High rate of fire Made of metal, really durable Adjustable stock Fore grip Weaver rails Really accurate with the stock sights
A bit heavy, but is no problem to me

Perfect for winter indoor fun
November 26, 2014
This rifle is very true to form and functions well. I got it to add to my collection of realistic blow-back pistols and it didn't disappoint. For target use indoors the accuracy is terrific but I am not a sharp shooter nor is ultimate accuracy a must. Great fun to shoot and I hope to add a scope or alternate site soon.

pretty sweet

This is a very nice rifle for the price. almost an exact replica of a M4 and loads of fun to shoot. not very accurate with the iron sight in my opinion. but i didnt expect much accuracy out of it, i plan on buying some accessories for it like a sight and foregrip just for some added realism and possible more accuracy
very accurate replica smooth semi-auto action easy to use lots of fun
not very accurate

Fun gun
January 3, 2014
fun gun to go out and shoot. haven't had a chance to sight in my scope yet due to the cold weather but I'm sure I'll find time to do so. solid gun design but for some reason when firing I did notice that the barrel was loose so I did have to go back and tighten up the screws and this solved the issue. I ended up running 72 rounds of bbs through before I changed co2. Those last 20 rds the accuracy fell a lot. and I dunno if its due to the cold or what but the trigger would hang up and I would have to pull back the bolt to fire another round. it was hit or miss on that but could get really annoying fire 3 nothing then you bull back the bolt fire bolt fire bolt fire then it will shoot off the rest off fine.. dunno if it persist but if so ill update.
Holds 16 rounds 8 per side of clip solid design not super loud compared to other guns I have fired great balance when holding
loose barrel out of box wobbly stock semi auto not working 100% have to to pull bolt back every other round or so...
