Has anyone experienced issues with headspace after installing a new barrel? I had a barrel spun up from x-caliber, installed at a local seemingly respectable shop. First trip to the range bolt would close 80% making it appear to be fully seated. I realized it wasn’t all the way when gun went click no bang and failed to extract the live round. Took it back and the shop showed me their go/nogo gauge functioning correctly but assured me they would investigate. They adjusted the head space again and even cycled several live rounds to prove it was functioning. After todays range trip I had 7 successful click, bangs and on the 8th the bolt failed to close and again failed to extract the live round.
Any of you guys with aftermarket barrels experience this? Scratching my head here and would greatly appreciate any input before taking it to another shop.

Does anyone know what is the exact length of the Sig cross 308 with the stock folded ?

I’m going to get out to shoot this thing this weekend. Very first rifle in this caliber.

I designed this for my Trax and solved the adjustability aspect as well as adding stability at the range, while keeping it light weight.

For the Cheek Riser, I went with a cantilever design so that it doesn’t interfere with the bolt when collapsing the stock.

Has anyone else done something similar?

Made from 6061 and hardcoat anodized. If I were to offer it to users on this reddit sub for $10, would anyone be interested?

Going on a hunt and would like to get a spare sig cross mag with the special follower. I know some people hate it and replace them and was hoping to snag one if you’ve got one laying around full mag. TIA

Proof is in the pudding. Would recommend the proof research prefit.

I just picked up a 308 sig cross this past week and I am looking for an optic. This is primarily a range toy with a minor amount of hunting if the need arises. I am looking for a lpvo, though I know most lpvo's dont exceed 10x mag. I want low magnification because I will be playing around with offhand shots at 50 to 100 yards on my home range. Though I would also like a bit of overhead on the top end to reach out a bit. I was interested in the Night Forced NX8 2.5 - 20 and Eotech Vudu 5 - 25. The Night Force is a bit expensive and I wish the Vudu had a slightly lower minimum magnification. Any recommendations that I'm missing? Thank you guys for the replies

OAL is 38cm (20,32 inch)

Inner diameter is 38mm (1.33 inch)

Am I crazy or is this the cheapest you guys have seen?

This action wrench uses a 1/2" socket extension bar and matches the 3 lug pattern of the bolt lugs to provide a robust, lightweight and low cost means to swap your barrel. You simply attach a socket wrench on the end as you torque off the barrel nut on the opposite side. This saves your receiver from damage to the index pin on the barrel assembly. It is made from 4140 chromoly steel, heat treated and black oxide finish. Made in NH.

I know my bipod is backwards but I have to have it that way to store it in my range case.

Huge favor to ask, would anybody that has the Strike Industries handguard be able to snap a picture of the handguard with a tape measure or ruler on it from the back of the handguard. Im building an 8.6 BLK Cross with an 8" barrel and im trying to see if the Strike handguard would line up a little better to chop down than the stock one. Thanks in advance!

Hey Yall hope all is well just bought a Cross 308. WC 16” I am waiting for the 10 day long wait to pick it up and wanted to get a scope for it now any recommendations I am working on a small budget for now maybe $200-$800 max but if it’s really worth possible do $1000. Thank you all

Has a Vortex Strike Eagle on it.

Hi, I bought my Cross chambered in 6.5 Creedmoor in December of 2025 and finally got around to shooting it for the first time last weekend.

I have it set up with a Vortex Viper HD 3-15x44 and a Vanward Hunter suppressor. Due to ammo availability the first load I tried was Hornady Superformance CX 120gr and accuracy out of that was *dismal*, 2 MOA and up.

Now I'm reaching out to ask this group for any positive experiences with lead-free loads, since that is what I am obligated to use for hunting.

Thanks in advance for your feedback

Added a new mag release from "maderifle.com" thought I should show it off.

Here's the link to the mag release

Here's a good video on YouTube showing the install

I was wondering if anybody in this group has purchased the strike industries X-Axis Handguard for their Sig cross? And if so, what was the inner diameter of that handguard? The website has diameter listed at 1.66” but does not specify OD or ID. I emailed Strike with no response so this group was my next thought. Thanks in advance for anyone with insight!

For guys like me who bought the Trax, but still want to shoot it on a bag. This is version 2 of my design.

Well I finally have my tax stamp and a barrel on the way. Building a 12” 8.6 just for fun. I can’t find a handguard that I really like. In fact the o my thing I can really find is the trax guard which isn’t what I am after. I may try to find a creative way of cutting down the stock one but the slot positions will make it a bit strange. Ideas please?

I am posting this because I could not find it. I have a standard Cross in 308 with the 16inch barrel. I also put the Vortex Razor LHT 4.5 to 22 with Vortex mid height match rings. I also added a BCM mod 1 break/comp muzzle device. Total weight unloaded was 8.37lbs.

I decided I wanted to put it on a diet because I hunt in the mountains and I was hoping a new barrel might fix the ammo sensitivity of the rifle.

So first,I swapped the buttock with the minimalist stock from Sig- weight 7.49 lbs

Then I put in a Proof Research prefit 16 carbon fiber barrel still in 308. Weight is now 6.61 lbs( I don’t currently have a muzzle device because I need a new crush washer)

Hope this helps someone.

I bought my standard cross in 6.5 CM on Valentines day and have about 350 rounds through it. Initially I bought a bunch of the Hornady 140 bthp match ammo from Scheels to load up on brass, break it in, and shoot steel. It shoots that stuff phenomenally (20 shots into 1.2” at 100). It is slow, about 180 fps slower than the box posted 2690 fps after break-in.

I have an antelope hunt in Wyoming this year and a mule deer hunt as well so I was hoping to run 127 Barnes LRX. I loaded some up with 43 grains of Staball 6.5 to 2.750” coal and it’s shooting 3” groups at 100. It’s getting too hot for load development so I bought a box of Hornady outfitter 120 CX and a box of Precision hunter 143 ELDX. The CX was about a 2.5” 5 shot groups and the ELDX was about a 2” 5 shot groups. These are both unacceptable to me. I considered trying H4350 but with this short barrel I would be around or under 2500 fps which is borderline for velocity with the LRX at 400.

I bought this rifle largely due having all the features I want and hearing about exceptional accuracy. I have great accuracy out of the bthp match ammo but that’s it so far. I hate to spend $50 a box to try others but I don’t like to develop loads in the summer. At this point I’m looking at taking my Ruger ranch in 6 arc for antelope and my 30-06 for the mule deer hunt because I can’t get my cross to shoot. They both shoot great with factory Hornady CX.

Mostly venting but also looking for suggestions on other hunting ammo to try. I’m generally a Hornady fan but am open to other mfg as well. I’m also generally a copper fan but I recognize that lead works.
