This BB replica is not only a great BB gun for plinking, but it makes a great target shooting and training pistol for S&W M&P owners.

Review: This is sick! - Ive had a lot of fun with this thing! It’s unfortunate that it doesn’t come with bbs and C02 cartridges but it’s not that much more to buy separate. I got these bbs for $3 https://www.desertcart.com/dp/B007II3FQS?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 they uselly go on sale so keep your eye on it. The gun feel and quality is very good and has some weigh to it. Be safe out there.
Review: 8/10 I would recommend - I got this on sale for $30 USD and was great for its price! I’ve owned this for 6 months. Shot over 1500 bbs. VERY IMPORTANT: Must use oil on top of c02 before install ( I use pellgunoil ). This prevents the seal from becoming frozen and cracking or breaking causing c02 to leak. Only issue I’ve ran into is that the bb sometimes doesn’t fire. Otherwise it’s decently powerful, accurate, and most importantly very fun. Cons: - mostly plastic - very lightweight - stationary slide / non blow back - not full size magazine (not to be confused with mag capacity) - may sometimes not fire bb - Simply a Air gun not a great training pistol, not able to replicate a real firearm. -c02 installation may be difficult due to part of the air gun being in the way. Pros: -Size similar to firearm counterpart -3 dot sight is decent - Accurate - good mag capacity - c02 lasts a good amount of rounds - great for plinking - price is reasonable - able to attach light/laser Overall I’m very pleased with my purchase.

## Questions & Answers

**Q: Plastic or Metal BBs????**
A: Metal.  I prefer the silver (zinc plated) Daisy BBs, they don't leave residue in the barrel like the coppery Crossman ones can.

**Q: Would i be able to do airsoft battles with this or is it to powerful**
A: It's to powerful

**Q: does the slide lock**
A: You are looking for blowback, which there are BB guns that have this and the slide does lock, all the way on last shot, you just need to make sure the gun markets itself with “blowback”. I got the Glock 19x 4.5bb .177 with blowback, awesome. Amazing replica

**Q: Is there any recoil?**
A: yes heavy recoil hurts my wrist

### ⭐⭐⭐⭐ New BB magazines shoot more accurate that original factory bb clip.
*by J***S on February 8, 2025*

Update: I bought a 2 pack of replacement clips for this BB gun and now the bb gun shoots straight like it should. Most people get a good bb magazine with their purchase, but I was unlucky. The original clip still shoots bbs in all different directions, but there is nothing wrong with the bb gun. I have tried several different clips with this gun and 1 clip shoots really really accurate, 2 shoot reasonablly accurate, and the one that came with it shoots all over the place. I have changed my review from 1 star to 4 stars because I can now get it to shoot straight with the replacement clips. I am still taking off 1 star because each clip shoots different. My advice is to get extra clips and test each one for accuracy. If they shoot straight and feed correctly, keep them, but if they don't, return the ones that are not satisfactory. If you get a BB gun that doesn't shoot straight like I did, just order a 2 pack of the extra bb magazines for this gun. Note: these extra bb magazines are recommended by Amazon for this gun and they also work great in my Crosman C11 bb gun. As for the people who complain about it being hard to screw in the CO2 and the gas leaking because of the way the handle opens, try taking the handle off carefully by gently pulling one side up and it pops off and goes back on. See attached pictures and video. Original review: This has to be the most inaccurate bb gun I have ever shot. The BBs don't shoot straight out of the barrel, instead they hit up, down, right and left, basically everywhere but where I am aiming. When shooting at a circle from 12 feet away, they are hitting all around the edges of the circle, but never in the center. With my other BB guns, even if the sights are off, the BBs hit in the same place and I am able to adjust my aim and shoot the center out of the target. It does, however, shoot with great power (over 410 fps) and is easy to work and the trigger pull is nice. It even looks pretty and like a real gun. This thing is kinda worthless as a BB gun for shooting things because it will not shoot the BBs out straight. The BBs curve in all different directions, so there is no way to adjust my aim. One shot will be high, the next low, the next up and to the right and then the next one curves to the left. By far this is the most inaccurate BB gun I have ever seen, but it sure does look nice and realistic. I love the fiber optic sights, too.
