Customer photo review of SIG MPX Mag Coupler

It works! After some delay (about a month or more), the items were shipped out and they work like a charm. Looks great on my Sig mpx. I will be buying more.

Customer photo review of Glock Mag Coupler (9mm/.40)

The Mag Coupler is fantastic. Works perfectly and installs in seconds. Did I need it? No. Does it look cool? 100% yes. Now I feel like Lee Marvin in The Dirty Dozen.

Quality couplers and easy to assemble. Made shooting this Ruger 10-22 much more fun! Definitely would buy more!

Customer photo review of M-LOK Match Saver

An inexpensive, quality product. High speed, low drag option for newer MLOK style fore ends. Mounts really low profile. Tight mounting and firm hold on shell. Very smooth to glide the shell to the chamber. An excellent design and quality materials.

Bought this for my Benelli M4 that I built for 3-gun. Perfect fit and function. Just in case I need that extra shot.

Fits like a glove. More importantly it works with my aftermarket magwell which most couplers fail at! 10/10!

Customer photo review of Glock Mag Coupler (10mm/.45)

+ I needed extended Glock .45/10mm mag couplers for my CMMG and there are VERY few options. Oscar Delta was one. - Actually receiving them took a little longer than I was comfortable with BUT - + Oscar Delta gave me good commo throughout including shipping and tracking. + The couplers are of solid make and one set holds two full mags firmly together. - They are too snug, especially on the backs of the mags and there's a bit of worrisome bowing: I hope they don't break with time, usage and weathering.

Got the mag clamp for my buddy, through the 9mm one on a set of .22 mags for the photo. Great alternative to metal mag clamps.

Customer photo review of FX-9 Blast Deflector V3

Great product. Works well. I had to modify it to fit my standard designed AR-9. I shaved down the inner side so it would fit flush and properly.

As good as (but not as fancy) as the High Tower Armoury product, at half the price.

Customer photo review of BX-1 10/22 Mag Coupler

The coupler is nice, fits tight and secure! I have two mag extensions and a two mag coupler from Oscar Delta. I like both products and would recommend them to all 10/22 shooters! I have had a couple tandemkross mag extensions and I ended up giving them away. Fyi

Customer photo review of PSA AK-V Mag Coupler

I bought 2 sets for my Scorpion and AK-V magazines, and both factory CZ and PSA magazines fit in these couplers very well and tight without having to crank down the screw. A surprise bonus: This coupler also worked for Stribog SPA magazines!

Customer photo review of MP5 Mag Coupler

Pretty nice for the price. I ordered two. If I were still jumping out of airplanes in the military or going into a real combat/police/SWAT situation I believe these might not stand up that level of abuse. However, for practicing reload drills at the range, they would seem to be a good deal. The shipping out of Canada was slowed by the postal strike but they eventually arrived well packaged and what I would consider of a reasonable quality for the price. Of note, on my MP5K clone the stacking of magazines in this manner makes it a bit hard to grab the front hand guard unless you stack them to the ejection port side. That is not a bad comment on this product but a reflection of the more compact design of the K model weapons. Stephen Lampasas, TX

Peace was broken when I opened the box when it was delivered I’ve emailed the company several times no response. No one’s contacted me not sure why the company is ignoring me fixing to dispute it with my credit card company.

These were a perfect fit for the Colt 9mm magazines on my Saint Victoria. Thanks for the quality!

Customer photo review of BX-1 10/22 Mag Coupler

These are very good quality magazine couplers, a small bit of filing to get the rough edges off and they fit tight and snug into the BX1 magazines, cheers guys

Customer photo review of Glock Mag Coupler (9mm/.40)

Absolutely awesome, I was concerned because it is 3d printed but damn this thing is solid! In the second photo you can see how much stronger and better made this is than his competition. In comparison I paid 10 dollars more for this one but it's easily 5x as strong and rigid than the other ones I have that are also printed, it took a while to get it because they had problems with billing etc but it was well worth the wait and he always responded to my emails and was understanding when I wasn't very understanding "started thinking I got scammed for a minute" but he made it right and I am so happy I didn't cancel my order. I will absolutely be recommending and supporting this company down the road I hope they do well because thier product is far superior to the competition! God bless!

Happy with my purchase, fits my mags very good, no need to modify, just needed a bit of grease to slide it in. Highly recommended.

Incredible mag coupler. With 40 round mags this means 80 lead smiles for miles in a matter of seconds with an extra special trigger!

Customer photo review of PCC Mag Coupler

Mag coupler is made really solid. It's a little tight when using it for .40 s&w, but it fits really snug. So there's not wiggle room or slipping when in use. However, mine order did take awhile to get here after it was in the states. I won't why but it was stuck for.days in one spot. Other than faster shipping, this is a great pick up!
