166 Insert/Outsert - 12 pack
The Pinnacle of Precision & Performance™ Altra Reinforced Concentric Outset System (A.R.C.O.S.) fits our Altra Arrows 166 Shafts and are machined out of 7075-T6 aluminum for unmatched durability and performance, with optimal fit options.
The insert secures into the arrow shaft at a depth of 0.875", while the outsert then threads directly onto the insert and encapsulates the leading end of the arrow at 0.43" creating unmatched durability. Essential rubber O-rings come pre-installed on the insert within the A.R.C.O.S., as they aid in locking the outsert in place which reduces vibration and improves concentricity between the outsert to the insert for a more precise arrow set up and down range accuracy.
Features:
- Comes in 12 pk QTY
- Available in four sizes - 250, 300, 350, & 400 spine
- 50gn Total Weight
- Accepts micro FMS insert weights
Altra Arrows highly recommends using a foam style arrow target when shooting arrows that have an ARCOS system, as the outserts can get stuck in filler of bag style targets which can damage the insert/outsert system or arrow.

The arrows that Altra are putting out are unmatched! Straightness, consistency in build, reliability... I can't think of an arrows that has performed better for me. If you're thinking about it, just try them... you won't regret it one bit!!
The Altra 27 Centrum Limited arrows have been a dream come true! They are by far the most consistent arrow i have found and make it so easy to build as close as possible perfect set of arrows that are completely true and consistent.
Got these arrows a couple a months ago, and so far some great arrows! Shoot as good as I can shoot and durable. Overall some great arrows so far.
These arrows group amazing right out of the box . Great product and no time wasted with nock tuning .
All of my arrows fly true and not a 1 in the bunch is off. Best arrows money can buy. No worries of consistency or weight differential. The spineless tech is second to none.
This is my second set of Altra Arrows and these don't disappoint. The penatration of these arrows with the insert/ outsert installed is unreal. Very smooth, consistent shooting. Im definitely sold on these and will be purchasing more very soon.
Works awesome! Fits other inserts weights as well. Thank you guys for making an awesome product!
Arrows are top notch. The best that I have ever shot. Nice merch also.
Great product worth the wait, prompt customer service as well
I opened the box cut to my length and threw the tips on. Threw caution to the wind and started shooting groups against my best go to arrows. My go to’s shot as normal and I was thinking it was going to be hard to beat that. MAN these Altra’s did not disappoint at all. Super tight out of the box and the best grouping I have ever had. I now have four arrows left after I shafted two of these Altra’s. So safe to say I am going to check out my cart after I’m done here and get a new dozen heading my way. I’m sold on these.
Figured I’d give these a shot for the price and am beyond excited. With my 28” draw and 125 grn points my arrows are at 490grns total weight and sShoot Straight As An Arrow thanks for a great product.
I’m really digging this outsert system. I wasn’t sure at first but dang it’s held
Up to some beating and haven’t had any issues.
