Part 2 covers fore grips, sling mounts, and various items that attach to weaver/picatinny rail. Included are mostly things I consider keepers, but also a few pieces of junk to avoid. I’ll keep it brief and try to link to sites with reviews for additional info. When included prices are rounded to the nearest dollar.
AR-15 Low Profile Vertical Fore Grip Aluminum. This is a quick release grip, had a storage area that’s well sealed, and I think it was around $20 or $25 from CTD. Aside from being a little heavy, this is a great grip for the price. If your weapon isn’t too heavy, I recommend this.
Tacstar Front Folding Gun Grip, $24. Difficult to get on the rail, took five minutes to get it back off the first time, so expect some saw/file work to make it fit right. The grip is comfortable and folds either direction, but rattles. I’m luke warm on this one.
OD Green Polymer Vertical foregrip Battle Grip 1913 Picatinny or weaver Rail Configuration, $8. About what you’d expect for eight bucks, but comfortable and solid enough, and I prefer it the to the folding grip above, especially if you’ll put in on something and leave it there awhile. Also good as a backup or loaner grip.
Tapco AR-15 Low-Profile Mini Vertical Forward Grip, $20. This is just a good grip and at an ok price – highly recommended. This knock off is of the same quality for a bit less.
UTG Low-Profile Deluxe Universal Picatinny & Swivel-Stud Bipod, $26. This bipod is outstanding for the price. Functional, solid, and rugged. I’ve been using one for a couple years and have several around the house. It attached to picatinny rail, but includes an adapter to attached to sling swivel studs. Back in the day when he used to do more of the short, useful gear reviews, Nutnfancy did one on this bipod.
TMS Rail Mounted QD Quick Detach Push Button Sling Swivel w/ Base. I got mine for about $12 a set, looks like they’re going for $17 now. These are nice if you want to move your sling around to different rifles. Of the set I got, one of the push buttons took a few seconds to set and could come out if it didn’t, so quality control may vary.
AR-15 Quick Detach Sling Swivel UTG Leapers Solid Steel 1 1/4″ Sling Loop Picatinny Mounting Base, $12. Does what it’s supposed to do, great price, recommended. Like a lot of UTG stuff it’s make of steel and heavy, but that’s why it’s tough.
AR-15 .5″ High 5.7″ Long 13 Slot Low Profile Riser Mount UTG Leapers Picatinny Rail Quick Detach Riser Mount, $8. Got this so I could put my Eotech 512 up a bit higher than co-witness – but the knobs that hold this to the rifle interfere and the red dot can’t be mounted! Not good for a 512, you may have better luck with other optics.
UTG 11mm to Weaver Adapter, Adjustable, $9. This clamps to .22 caliber or airgun rifles with the narrower 11 base so you can attach a red dot or use regular scope rings. Very nice if you want to move scopes around to try them out on different rifles. It works exactly as advertised and you can’t beat the price, recommended.
UTG Full Size G36 Picatinny Rail Set, $13. I used these rails to attached to various synthetic stocks that didn’t already have them so I can attached grips, bipods, lights, etc. Does the job, fair quality, won’t break the bank.
