DPMS Full Auto SBR CO2-Powered BB Air Gun with Dual Action Capability

I've had this rifle for abt 2 weeks. After reading tons of reviews and getting some serious trigger time myself, I've come up with the following observations/recommendations: Feels very real in your hands. Flip up sights are cheap junk and really don't look like they belong on such a great looking rifle. Crossman should really pony up and put some decent flip-up iron sights on this thing. How much could it cost at such volumes? Anyway, I took them off and replaced with cheap red/green dot scope before the first loading. https://www.amazon.com/gp/product/B019MN7N5U/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 After handling his rifle for a few hours now I believe it would be excellent for introduction training for a real AR. All controls work very close to a real AR (except fwd assist which rarely gets used anyway). Trigger is a bit stiff and appears to behave like a 2-stage trigger. At abt 90% of trigger force applied, there's a faint click, then a bit more squeeze and it fires. Not sure if this was an intentional feature but it's very consistent and I like it. At 30 ft, with fresh co2, I'm grouping 25 rnds within an inch in semi-auto (with a rest). Holds elevation pretty well for first 6 mags. Elevation drops 2-3 inches @ 30 ft. on last (7th) mag. When co2 gets low, rifle occasionally does some weird stuff like double firing or dry firing. When co2 gets really low, you have to use the charge lever between shots, but by then it's time to replaced co2 anyway. From what I've heard, to extend the life of the rifle, you shouldn't run full auto with fresh co2 cyls or near empty ones either. Shoot the first mag in semi-auto then switch to full-auto for a couple of mags, then back to semi-auto until co2 is gone. Also, not too much full auto until you have a few hounded rnds thru it. Seems like good advice since moving parts need to wear-in. First 1500 BBs were Hornady Black Diamond since I heard they load easier (and they are). Speed loader takes a little getting used to, but after you get the hang of it, it's great. I spray a little Rem oil in the loader, load it between 1/2 and 3/4 full then another quick spray of oil. Then shake it to distribute the oil around. Switched to Daisy zinc coated BB's since local store was out of Hornady's. They are a little more difficult to load but so far no issues with first 1000 rounds. Daisy grouped as well as the Hornady's. When speed loader plunger jams, don't force it. Just flip it upside down (while still connected to mag) and gently work the plunger until it un-jams, then flip it back upright and continue. At first it didn't seem to shoot more than abt 75-100 rnds before running out of co2 (semi-auto only). When removing right (secondary) cylinder, a LOT of co2 escaped. Inspected piercing pin and it looked OK. Next time removing co2 cylinders, I loosened the right cyl very very slowly. Noticed after abt 1/4 turn loosening, the right cyl got cold but wasn't leaking. I was then able to fire another 75 or so rnds. Next time I loaded 2 new cyls, I tightened the left cyl normally. On the right cyl, I tightened until it was abt as tight as I could get it with the supplied wrench, then backed it off exactly 1/4 turn. Now it works as it should. I've ran 6 cyls thru it this way and so far so good. There's something odd going on inside the mag that makes the right cylinder not flow if cyl is screwed on really tight but this appears to be a good work-around so far. Microscopic manual says to oil after ~1000 rnds. That's what I did. Maybe Crossman wants to parts to wear-in before oiling?? I applied pelgunoil to the co2 tips and everything else that moves including the seal. Feels significantly smoother now. I've heard pelgunoil is actually non-detergent ATF. When the pelgunoil tube runs out, I'll probably refill it with ATF and keep rolling. EDIT: After a hit more research, looks like silicone oil is supposed to be used on the green seal, in the cyl where green seal slides into and on the seal at output of the magazine. I'll be switching over to silicone oil for these parts. Still using pelgunoil for tips of co2 cyls. IMHO, this was a steal at $145. Even at $180 it's still a bargain. I've had a lot of fun with it and actually feel I'm improving my target acquisition time and muscle memory. Hats off to DPMS/Panther Arms/Crossman for releasing such a BB gun.

Great buy for the price looks very good build it feels good in hands very easy to load and use. The size it the perfect fit. Good accuracy and easy to adjust sites

Husband was ecstatic to open this for Christmas...he was so happy. He said the quality is top notch. The look of it is great and the range is awesome. There has been no jamming and the power is amazing. He said for the money, this is an amazing air gun.

Purchase this after a friend of ours son got a similar unit. Right out of the box this thing is cool. It has good weight even balance and really looks sharp. We loaded up with two cartridges of CO2 and loaded the magazine with bb's. Shooting this is a lot of fun. It would just be a little nicer if it held a few more bb's. Before you know it they're all shot out and you're loading it again. I would buy another one of these in a heartbeat.

Bought several years ago for my younger cousin. Still works great, and looks cool. His DPMS is fully kitted at this point. Surprisingly accurate and the 1,400rpm is very fun. Only the 25 BB magazine empties in a 10th of a second so prepare to reload a bunch

After almost 4 years of owning this gbbr ive had zero issues with the gun itself. Shoots smooth as butter, sounds crisp and just satisfying, only thing im not a fan of is the magazine, the co2 compartment door fall off on occasion but its an easy fix with quick release tape. But other than that, the gun and the magazine have held up amazingly and I would definitely recommend this for any interested buyers 10/10

Pros: This gun is so much fun to shoot! Full auto mode leads to spontaneous giggling from the shooter and spectators alike. Weight and balance are very much like the real thing. Charging handle, safety/fire selector, are very realistic, although the forward assist is non-functional. Did I say how much fun it is to shoot this thing? Surprisingly accurate. The attached photo is from my 1st 100 shots. The tight clusters are from 3 25-round full auto bursts. The others are from semi-auto file as I tried to use the flip-up sights. All were at 30 ft. Cons: The flip-up sights aren't much use, at least for my eyes. In most lighting conditions, I found that the smooth inside surface of the cylindrical rear sight aperture was too reflective, causing enough glare to block out the front post sight entirely. It is far too loud to be back yard friendly, if neighbors are close. The loading tool is temperamental at best, jamming frequently. It is made of light plastic that feels like it will break at any moment. When it's functioning properly, it is a major improvement over hand-loading, but of 10 loading attempts, I only had 1 load the full 25 BBs without failure. Final take: If you are interested in this gun at all, BUY IT NOW. Once you fire it, you will honestly wonder why you waited at all. Ignore the loading tool. Buy your BBs in the dispenser with the little tapered spout. Just hold the bb follower back with your thumb (manual says "lock it back", but that's a misprint), tip the mag so the top end is a bit downward, and pour the BBs into the feeding hole till the slot is full. Release the follower. Don't worry if you spill some, cuz you'll be spilling a lot more real soon. Order extra magazines! The 25 rds go so fast, you'll be glad you spent the $50 a piece, just so you can keep shooting. Mount a Red Dot reflex optic or Laser for better point and shoot target acquisition.
