No reinforcements should be required to run a 7kg spring but if you are putting it in an older, more brittle longshot shell then you may want to think about reinforcing the boltsled with some aluminium plates and araldite just to be safe. A stock longshot shell should be able to take up to 18kg spring-load, but at that kind of force you will most definitely need a few aftermarket internal parts like a new breech, plunger head, boltsled ect.
Yeah, I have some basic polycarbonate internals (plunger head, rod, and boltsled), and rubber padding. With those reinforcements done, I'm now just concerned about the back plunger area, and the catch.

The back plunger cap (mickey mouse piece) doesn't actually serve much of a purpose as a structual part, but is really there to keep your spring(s) aligned and guide your plunger rod. If you look at where the cap sits then you will see that there is a strut in the shell that actually takes some of the stress from the spring, so you could just take some extra precaution and fill in the space behind that wall with epoxy putty. As for the catch, ive been running she stock catch at 18 kg for quite a while and it is showing absoulutely no signs of wear. You should be good just upgrading the catch spring.
Is it actually necessary to reinforce the shell with epoxy putty? Like, has anybody had their shell break on them?

Would just filling the gaps be enough to prevent a breakage? This is now the weakest part of my Longshot (I've either reinforced or bought polycarbonate parts for the rest), and I really don't want it failing on me. The project goal is to make this blaster last at least 4 years, or roughly 15 000 shots.
