Good Sten MK2 kit, slow shipping

I ordered a Sten MK2 parts kit. The quality of the parts was solid, everything was there. Building it was straightforward enough. My only real gripe was the shipping time; it took 8 days to get to me in Arizona, which felt a bit long. Customer service was helpful when I called to check on it, though.

Decent value on parts

I was looking for a good deal on some specific parts and found them here. I grabbed a recoil spring set and a new barrel shroud for my Sten. The prices were fair, especially compared to some other places I checked online. Didn't see any big discounts, but the base price was competitive. Shipping was standard, not super fast but not slow either. The parts themselves were good quality, fit right into my build. Felt like a solid purchase for what I paid.

Excellent MP-28 semi-auto kit!

I just finished building my MP-28 semi-auto kit and it's fantastic! The parts fit together perfectly and the instructions were clear. The finished product looks and feels amazing. I was really impressed with the quality of the reproduction parts. I will definitely be buying from Indianapolis Ordnance again, probably for a Lanchester kit next! Really happy with my purchase.

is there like, a military or vet discount for these guys? saw some stores offer that.

S Shane 1 month ago

yep, they do. you usually have to email them with proof of service, and they'll set you up with something, usually 5-10% off. not a huge discount, but every bit helps.

P Phil Brooks 1 month ago

i got a small discount as a vet. just reach out to their support, they'll tell you what to send.

what's their return policy like if i order something and it's not quite right? for like, a smaller part.

F Faith 1 month ago

returns on machined parts are usually fine if you haven't messed with them. i returned a barrel shroud once that i accidentally double-ordered, no problems. just make sure it's in the original condition.

I Ivy Patel 1 month ago

yeah, as long as it's unused and in the original packaging, you should be good. they're pretty reasonable, just don't try to send back something you've already cut or welded on.

so, what's the deal with their 'semi-auto conversion bolts'? is that like, a drop-in thing or do you gotta be a wizard to make it work?

P Priya C. 2 months ago

not drop-in, no. it's for semi-auto builds, so it's designed to only cycle one round at a time. you'll still need to build the rest of the semi-auto internals around it. definitely not a 'convert your full-auto' part, those are big no-nos.

F Faith Reyes 2 months ago

it's part of the BATF compliance for a semi-auto build. you still need to know what you're doing with the rest of the kit. they aren't selling anything that lets you easily make a full auto.

hey, anyone know if they ship these kits to california? seems like a tricky state for gun parts.

R Renee 2 months ago

yeah, they do actually. i got a smaller parts kit from them a few months back, no issues with CA. the kits themselves aren't firearms, just parts.

O Omar 2 months ago

i think as long as it's not a complete firearm, just the parts for a build, it should be fine. they say they're BATF compliant so that usually means they've thought about state laws too.

do they ever do free shipping? or like, any coupon codes out there? seems pricey to ship a full kit.

L Lisa 1 month ago

i think they sometimes do free shipping on the full build kits during sales, like around black friday. but public coupon codes are super rare, almost nonexistent from what i've seen.

T Tom 1 month ago

nah, don't hold your breath for coupons. they're pretty stingy with those. best bet is watching for a holiday sale, sometimes they'll auto-apply a small discount or free shipping then.

how long does it usually take for a sten kit to ship out? thinking about grabbing one but impatient lol.

C Cody Foster 2 months ago

lead times can vary, especially with the bigger kits. i ordered a trunnion last year and it took about a week to get a shipping notification. for a full kit, i'd probably expect a bit longer.

T Tom Reyes 2 months ago

mine took almost two weeks to even leave their shop. it's not amazon prime, for sure. plan accordingly if you have a build weekend in mind.

thinking about getting a sten mk2 kit. how does it compare to the stuff apex gun parts sells? quality-wise mainly.

F Faith Ito 1 month ago

i've built from both. indy ordnance parts are generally new production, so fit and finish are usually really good, very consistent. apex is more surplus, which means you get what you get, sometimes it's great, sometimes it needs more work. depends if you want original look or reliable new build.

J James Beaumont 1 month ago

indy ordnance is usually way better for actual 'building' if you want everything to fit well without a ton of fiddling. apex is good for original parts if you're trying to restore something specific, but for a semi-auto build, i'd lean towards indy ordnance.

do these kits come with instructions? never built one of these before and kinda nervous.

M Mark 2 months ago

most of the full build kits do come with instructions, yeah. they're pretty decent, usually step-by-step guides. but you'll still need some mechanical aptitude and the right tools. it's not like assembling ikea furniture.

J June 2 months ago

mine came with instructions, but i also watched a bunch of youtube videos. definitely helps to see it being done, especially if you're new to it.
