Channel fans and family — I love seeing advancement in firearms, but what I can’t stand (and neither can my wife) is totes of gun stuff that fell out of fashion or just doesn’t fit the rifle anymore. Admit it: we all have them. M-LOK and ARCA have largely replaced old-school Picatinny for a lot of modern setups, which leaves a real question: what do you do with a perfectly good swivel-stud bipod you don’t want to toss?
Adapters in this video: Sunwayfoto MBA-01 and ABA-01 (with SDC-50). Precision accessories: Anarchy Outdoors (code SlavGuns on Anarchy-manufactured only). Everyday gear lists: SlavGuns Amazon. Support the channel: join on YouTube.
The bipod money pit
A good bipod is nice-to-have for any rifle owner and a must-have for longer-range precision or matches (PRS, NRL, and the rest). Entry-level good ones land around the $100–$150 range on camera; step up and you’re looking at $300–$500 before you even glance at the stratosphere. Most of us follow “buy once, cry once” — until the new rifle won’t take the old swivel-stud bipod and you’re crying twice.
Past default: sling swivel stud. Today’s default on a lot of bipods: Picatinny, and for me most of mine run an ARCA adapter. You can buy a Picatinny-to-swivel-stud adapter per rifle… or keep a few good bipods and adapt them so they move between guns.
MBA-01 — put a swivel stud on M-LOK
Most modern sporting rifles lean M-LOK instead of studs. Options: buy a new M-LOK bipod, add a Picatinny section, or — if you already own a swivel-stud bipod — install the MBA-01.
- Metal plate with a built-in stud
- Attaches across two M-LOK slots — drop in, screw down, you’ve got a swivel stud
- Called out on camera as well-made and around $15
Catch: it’s still a per-rifle solution. You can move it, but ideally you’d want one on each gun you keep a stud bipod on.
ABA-01 + SDC-50 — modernize the bipod instead
If the rifle already has Picatinny or M-LOK with a Picatinny/ARCA section, flip the problem: adapt the bipod. The ABA-01 is similar in spirit to the MBA-01, but it mates to the bottom of Sunwayfoto’s SDC-50 plate. That plate works with both Picatinny and ARCA sections (and similar industry-standard plates). On camera I called out preferring the SDC-50 style with the quick-lock on the side — same family as what shows up on Sunwayfoto tripod kits.
Price is more than fifteen bucks, but still way under buying another quality bipod. Clip the ABA onto the bipod’s stud, tighten, and suddenly that old Harris-style bipod slides onto Picatinny or ARCA. ARCA bonus from the video: loosen, slide to where you want it on the rail, retighten — plus room for bags, barricade stops, and other rail accessories.
Outdoor takeaway
Unboxing + features + outdoor impressions: keep the bipod you already paid for and spend adapter money instead of bipod money. Would you adapt, or are you going to be the more typical gun owner and just buy more stuff? There’s no wrong answer — your spouse might disagree.
Bottom line
Sunwayfoto’s MBA-01 puts a swivel stud on M-LOK rifles; the ABA-01 + SDC-50 turns a swivel-stud bipod into a Picatinny/ARCA bipod. Both are cheaper than replacing a good bipod when the mounting standard on your rifle changed.
Keep on squatting. I’ll see you in the next video.
Would you adapt the bipod you already own, or buy new every time the rail standard changes?
